Abstract:
An electric vehicle includes a regenerative brake and a mechanical brake. The vehicle also includes a wheel bearing unit and a load sensor associated with the wheel bearing unit. The load sensor is configured to detect a load that acts between a road surface and a tire along a direction in which the vehicle travels. The vehicle also includes a load-responsive regenerative brake limiter configured to reduce a braking torque generated by the regenerative brake when an output of the load sensor reaches a preset value. A maximally actuator may be configured to calculate a maximum possible regenerative braking torque for the regenerative brake based on a rotational frequency of a wheel and a state of charge of a battery unit and to actuate the regenerative brake at a maximum torque within that commanded range.
