Patent attributes
An overrunable test vehicle including an electronically-controlled anti-slip braking system for reducing wheel slip during rapid deceleration comprising: a chassis, at least one electric motor connected to a first axle, a hydraulic braking system connected with the chassis and at least a second axle, a rotational speed sensor for determining a rotational speed of a connected axle, a ground speed sensor, and a controller connected with the electric motor, the hydraulic braking system, the rotational speed sensor, and the ground speed sensor. The controller is configured to calculate a difference between the rotational speed of the axle and the ground speed of the chassis to determine a slip threshold of the wheels, actuate the hydraulic brake system to apply a first stopping force, control at least one motor parameter of the electric motor to apply a second stopping force. The first and second stopping forces combined are less than the slip threshold of the wheels such that the chassis rapidly decelerates free of a wheel slip condition.
