Intelligent Child-Safety Inhibition framework for preventing accidental vehicle activation2026-26-0013To be published on 01/16/2026
Modern vehicle technologies such as keyless entry, push-button start, digital switches have made it easier and more convenient to operate cars. However, this ease of operation has also introduced new safety concerns, particularly the increased risk of accidental operations by children. This can lead to unintentional vehicle movement, injuries, and even fatalities. Existing safety features (e.g., unattended child presence alarms) mitigate entrapment risks but do not prevent children from unintentionally starting or shifting while inside. This paper proposes implementation of a solution for child-safety system which inhibits certain functionalities to prevent accidental operations by underage occupants. The proposed system combines multiple existing technologies like weight sensors, seat position detection, facial recognition, in vehicle camera tracking to determine the child presence. With this, certain operations can be temporarily inhibited, or the vehicle can ask for secondary

CAE Method for Automotive Remote Keyless Entry System Range Simulation2022-01-014703/29/2022
Remote Keyless Entry (RKE) systems are widely used as the standard solution for conveniently accessing vehicles by remote control. The RKE system consists of a key fob RKE transmitter and in-vehicle Remote Function Actuator (RFA) module. The RFA module receives a signal from the RKE transmitter to perform remote control functions, and transmission range is an important requirement to evaluate the performance of the RKE system. To accelerate product development cycles and reduce engineering costs of physical test, a computer aided engineering (CAE) method has been developed to predict transmission range of the RKE system. Firstly, the detailed computational electromagnetic (CEM) models of the transmitting and receiving antennas were developed to ensure that the far field radiation patterns were in good agreement with test data. Secondly, the full vehicle meshed model and the articulated human model were introduced to the CEM models to reflect the physical test environment. Lastly, the

Water Avoidance Design Strategy for Capacitive Exterior Handles2019-36-018701/13/2020
Nowadays, capacitive handles are increasing their use in high-end commercial vehicles. This particular handle applies a technology that permits to unlock and even lock the vehicle without a key. As benefit for current life, the customer has the possibility to access and close the vehicles more efficiently and faster, just possessing the key in the pocket or any close compartment that the user is carrying, for example, bag, purse, backpack. Even though, the design of capacitive exterior handle must follow several design strategies to avoid nonfunctional in rainy climate. Water could work as a blocker for the sensor signal captured, special design strategies that must be taken in order to minimize that the liquid could ingress the handle and even be retained on the region that sensor is located. On this two-piece handle not only the parting line location, drain holes and a favorable drainage for liquids inside the handle must be designed, but also a control on the painting capacitance is

A Low Profile Loop Antenna Design for Automotive Applications2017-01-169603/28/2017
This paper proposes a novel antenna design for automotive communication applications. The antenna design combines a resonant Alford loop with folded dipole elements to allow for efficiencies that are higher than electrically small loop antenna designs. The Alford loop provides the horizontal polarization and omnidirectional pattern coverage on the horizon which is desired for remote keyless entry and other narrowband automotive applications. With the use of folded dipole elements, the design allows for low profile mounting desired by automotive styling.

Peugeot Fractal demonstrates a new take on sound design15AUTP11_1011/01/2015
Peugeot used the 2010 SR1 concept to introduce its i-Cockpit touchscreen-based system, designed to control heating and ventilation, navigation, audio, connectivity, and the trip computer. The first-gen system entered production in the 2012 Peugeot 208. The company took the i-Cockpit concept one stage further in the Fractal electric urban coupe concept at the 2015 IAA Frankfurt Show, to include sound. The concept plays a “sound signature,” created by DJ and sound designer Amon Tobin, which is triggered when the driver opens the car using the smart watch remote locking system. “Behind this concept of an electric car-that is not really new, there was this question that electric cars emit no sound,” explained Matthias Hossann, Head of Concept Cars and Advanced Design at Peugeot.

Introduction to Vehicular Embedded Security2009-01-091604/20/2009
For new automotive applications and services, information technology (IT) has gained central importance. IT-related costs in car manufacturing are already high, and they will increase dramatically in the future. Yet whereas the area of safety and reliability has become a relatively well-established field, the protection of vehicular IT systems against systematic manipulation or intrusion has only recently started to emerge. Nevertheless, IT security is already the base of some vehicular applications, such as immobilizers or digital tachographs. To securely enable future automotive applications and business models, IT security will be one of the central technologies for the next generation of vehicles. After a state-of-the-art overview of IT security in vehicles, this paper will give a short introduction into cryptographic terminology and functionality. This contribution will then identify the need for automotive IT security while presenting typical attacks, resulting security

Building Secure, Survivable Infotainment and Telematics Systems2006-21-001610/16/2006
As infotainment and telematics systems become increasingly connected to the outside world, questions arise about reliability and security. Can new software be downloaded, or existing software updated, without compromising system performance and availability? Can the existing behavior of the system be guaranteed when the user downloads content or applications from an untrusted source? Meanwhile, the software in these systems is becoming extremely complex, introducing additional concerns about performance, reliability, security, and time to market. This paper examines several methods, including recent advances in software partitioning, that not only safeguard against both internal and external threats, but also allow systems to reliably support new content and services. The net result: systems that can dynamically adapt to evolving consumer requirements, without compromising the reliability and security that both consumers and automakers demand.

Alternatives to Keyways in Motion SystemsTBMG-1003310/01/2006
The age-old tradition of using shaft keys in mechanical drives has served the power transmission industry well for many years. When appropriately sized, it guarantees that virtually no relative motion can take place between a shaft and its respective shaft hub in a unidirectional continuous motion application. Today’s increasing demands for speed, precision, and small size have changed the standard for shaft locking devices, and challenged motion components manufacturers to develop new methods of keyless shaft locking for dynamic loading. As motors and drives become increasingly capable of rapid acceleration and rotary positioning accuracy in smaller and smaller packages, backlash, stress distribution, and balance have all needed to be addressed in shaft locking devices, in many cases rendering the shaft key obsolete.

A New State-of-the-Art Keyless Entry System98038102/23/1998
A new keyless entry system, for automotive security and comfort applications, has been developed. The system utilises a single chip transponder for vehicle immobilisation, keyless entry and remote control functionality. The transponder system can be embedded into a key fob or an ISO smart card. System security and communication speed is provided by an advanced anti-collision protocol in combination with sophisticated challenge response and uni-directional protocols. The system can be activated by using either a push-button transponder, where long range access to the vehicle is provided, or by touching an actuator near the door or trunk. Due to the inductive coupling between the transponder and the vehicle mounted antennas, the vehicle door or trunk opens on successful verification as if there were no locks. Additionally, inside the vehicle, the transponder can be used as an immobiliser.
