BRAKE CONTROL DEVICE

摘要

A brake control device is provided that can reduce the driver's uncomfortable feeling even when operation amount detection means is broken down. When abnormality determination means 71 for determining abnormality of a pedal stroke sensor 3 determines that the operation amount detection means is abnormal, a predetermined regenerative torque is set to the generator (rotary electric machine) 9 upon sensing the pressing of a brake pedal by a stop lamp switch 4, and a predetermined maximum regenerative torque is set to the generator (rotary electric machine) 9 upon sensing the pressing of the pedal by a cruise control switch 42.

主权项

1. A brake control device, comprising:
an operation amount detection unit for detecting an operation amount of a brake pedal; an abnormality determination unit for determining abnormality of the operation amount detection unit; a first sensing unit for sensing that the brake pedal is operated by an amount exceeding a predetermined first operation amount; a second sensing unit for sensing that the brake pedal is operated by an amount exceeding a predetermined second operation amount, the second operation amount being larger than the first operation amount; and a regeneration control unit adapted to set a regenerative torque corresponding to the operation amount detected by the operation amount detection unit to a rotary electric machine when the abnormality determination unit determines that the operation amount detection unit is normal, and also adapted to make information from the operation amount detection unit invalid when the abnormality determination unit determines that the operation amount detection unit is abnormal, thereby setting a first predetermined regenerative torque to the rotary electric machine upon sensing of the operation by the first sensing unit, or a second predetermined regenerative torque which is larger than the first regenerative torque to the rotary electric machine upon sensing of the operation by the second sensing unit.
