System Description
WARNING: This page is about a different variant/trim than selected.
- The brake ECU calculates the total braking force needed, based on the master cylinder pressure in the brake actuator and brake pedal stroke sensor generated when the driver depresses the brake pedal.
- The brake ECU computes a part for the required regeneration brake force from the total braking force, and sends the result to the hybrid vehicle control ECU.
- The hybrid vehicle control ECU executes to the minus torque to MG2, and carries out the regenerative brake functions.
The brake ECU controls the brake actuator solenoid valves and generates the wheel cylinder pressure, which is the actual regenerative brake control value subtracted from the total braking force.
- The brake ECU outputs a request to the hybrid vehicle control ECU to effect motor traction control while the vehicle is operating under TCS function control. The hybrid vehicle control ECU controls the engine, MG1, and MG2 in accordance with the present driving conditions in order to suppress the motive force.
