Abstract
An ECU which includes a receiving portion that receives a control signal related to braking of a vehicle transmitted from an external ECU installed outside the ECU and a yaw rate estimation portion that estimates a yaw rate of the vehicle, based on a vehicle speed and steering angles which indicate turning angles of a steering wheel of the vehicle or turning angles of a wheel.
Claims5
A brake control unit for controlling braking of a vehicle, comprising:
- a receiving portion that receives a control signal related to braking of the vehicle which is transmitted from an external control unit installed outside the brake control unit;
- an estimation portion that estimates a yaw rate of the vehicle, based on a vehicle speed and steering angles which indicate turning angles of a steering wheel of the vehicle or turning angles of a wheel;
- and
- a controller which controls degrees of intervention of the control signal received by the receiving portion in a brake control, based on a deviation between the yaw rate estimated by the estimation portion and an actual yaw rate measured by a yaw rate sensor, wherein the controller is configured to determine whether or not to activate a brake control by the control signal received from the external control unit, based on the deviation.
