The Toyota Hybrid System uses a high-voltage battery pack, ranging between 276 and 288 V. There has been a continuous, gradual improvement in the specific capacity of the traction battery. The original Prius used shrink-wrapped 1.2 volt D cells, and all subsequent THS/HSD vehicles have used custom 7.2 V battery modules mounted in a carrier.
The electromagnetic parking sensor (EPS) was re-invented and patented in 1992 by Mauro Del Signore. [2] Electromagnetic sensors rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once an obstacle is detected, the sensor continues to signal the presence of the obstacle even if the vehicle momentarily stops.
The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
The system components consisted of a control switch, indicator light, four shock absorbers, shock absorber control actuator, shock absorber control computer, vehicle speed sensor, stop lamp switch, with a throttle position sensor and a steering angle sensor on TEMS three stage systems only. All the absorbers are controlled with the same level ...
Lexus backup camera system showing the parallel park setup screen. Intelligent Parking Assist System (IPAS), also known as Advanced Parking Guidance System (APGS) for Toyota models in the United States, is the first production automatic parking system developed by Toyota Motor Corporation in 1999 initially for the Japanese market hybrid Prius models and Lexus models.
Vehicle Dynamics Integrated Management (VDIM) is an integrated vehicle handling and software control system developed by Toyota. It involves an omnibus computer linkage of traction control , electronic stability control , electronic steering , and other systems, with the intent of improving responsiveness to driver input, performance, and ...
This correction enables a larger maximum permissible air gap at the speed sensor. On a module m = 1 target wheel these new sensors can tolerate an air gap of 1.4 mm, which is wider than that for conventional speed sensors on module m = 2 target wheels. On a module m = 2 target wheel the new speed sensors can tolerate gap of as much as 2.2 mm.
A yaw rate sensor that measures the rotation rate of the car. The data from the yaw sensor is compared with the data from the steering wheel angle sensor to determine regulating action. [47] A lateral acceleration sensor that measures the vehicle's lateral acceleration. This is often called an accelerometer. Wheel speed sensors that measure ...
