Tokai-Rika In-Vehicle Technology Application Innovations
These are 4 Innovations recently developed by Tokai-Rika that would be of interest to new EV OEMs and integrators. If interested directly contact Tokai-Rika USA or Japan.
Digital Key Doubles as Child Presence Detection System: The European New Car Assessment Program (Euro NCAP) started testing child presence. However, the detection system uses expensive millimeter wave radar. Tokai Rika’s design target was to use an onboard UWB digital key device as a sensor to create a low-cost child presence detection system.
The original detection algorithm using the stationarity of phase difference between antennas improves the performance of detecting body motion. The multi-antenna technology that ensures the characteristics of antennas installed close to each other in the radio wave bandwidth improves the accuracy of angle detection, enabling fewer units to detect a living body in and out of a car. (Two patents applied).
Remote Control Unit, Camera, and Image Integration ECU: There is a need for remote 
control mobility systems as a solution to social problems such as harsh work environments and resulting labor shortages in various fields. The benefits of employers are recruitment appeal, less labor cost and fewer labor accidents and benefits for workers are efficient use of in-between time, more career choices, and avoidance of harsh work environments.
This all-in-one control unit incorporates switches, a display, and a sensor that have the same strengths as those installed in an actual car. The switches also have realistic operating feelings.
The image processing technology is used for the remote monitoring system of a self-driving bus (Tokai Rika offered the system in some demonstration experiments). In this in-cabin monitoring
system concept, when detecting any passenger’ unsafe behavior, the monitoring system informs the supervisor to prevent the passenger from falling. The system is also available for existing regular bus services.
Precise Parking at a Glance – Wireless Charging Support for EVs: In wireless EV charging, a driver must align the receiver coil with the transmitter coil by instinct because the receiver coil is inside the car and the transmitter one becomes invisible as the driver parks the car. Misaligned coils can cause problems such as retry parking and power loss.
The UWB high precision ranging function measures the distance and direction between the transmitter coil and the receiver coil to give parking instructions to the driver. On board, UWB devices for digital-key can serve as a low-cost charging support system. Multiple UWB units work together to measure distances accurately.
Next Generation In-wheel Motors Electric Current Sensor Module: This came out of a collaboration between e-Gle and Tokai Rika for the Creation of an innovative electromechanical in-wheel motor that integrates a motor, an inverter, and a cooling system. Current Sensor and Bus Bar Technology with current sensor and busbar technology.
