Fail-Safe Chart
- FAIL-SAFE FUNCTION
- If a malfunction occurs in the skid control ECU, sensor signal, or actuator, the normally operating parts will maintain brake control.
- If the brake control is stopped under such conditions as when trouble occurs with a hydraulic pressure source, the pressure generated in the master cylinder by the driver is applied to the wheel cylinder to ensure braking force.
- A power back-up unit is built in as an additional power source to supply stable power to the system.
- If the regenerative brake alone does not operate under such conditions as a communication error with the HV ECU, control is switched so that all braking force is generated with the hydraulic pressure brake.TROUBLESHOOTING CHART
