Wheel speed sensors detect wheel speeds of a plurality of wheels (i.e., a wheel speed of a front left wheel, a wheel speed of a front right wheel, a wheel speed of a rear left wheel, and a wheel speed of a rear right wheel), respectively. A braking control apparatus controls driving of an electric motor. The braking control apparatus drives the electric motor to increase a braking force when the wheel speed sensors detect wheel speed pulses from at least two wheels after a start to maintain the braking force.

A variable load calculator calculates a variable load command VL based on AS pressure and a predetermined table. A vehicle deceleration calculator calculates vehicle deceleration α based on a brake notch command BN and a predetermined table. A required braking force calculator calculates required braking force BL by multiplying a weight indicated by the variable load command VL and the vehicle deceleration α. An electric braking controller calculates an electric braking pattern in accordance with the required braking force BL and then transmits the electric braking pattern to an inverter controller. The electric braking controller calculates an electric braking force produced by operation of the electric motor and then transmits to a subtractor as feedback BT the electric braking force adjusted in accordance with a speed of the electric motor. The subtractor transmits to a mechanical brake as a mechanical braking command a result obtained by subtracting the feedback BT from the required braking force BL.

A method and system for jerk-free stopping of a motor vehicle to automatically bring the motor vehicle to a standstill at a predetermined destination point, wherein the deceleration exerted on the motor vehicle is ascertained, entirely or in part, as the difference of a spring force component and a damping component, with the damping component being proportional to the present vehicle velocity.

A system for navigating a host vehicle may receive an image representative of an environment of the host vehicle and determine a planned navigational action for accomplishing a navigational goal of the host vehicle. The system may identify a target vehicle, determine a current speed of the target vehicle, and assume a maximum braking rate capability of the target vehicle. The system may determine a next-state distance between the host vehicle and the target vehicle that would result if the planned navigational action was taken. The system may implement the planned navigational action if the host vehicle may be stopped using a predetermined sub-maximal braking rate within a distance that is less than the determined next-state distance summed together with a target vehicle travel distance determined based on the current speed of the target vehicle and the maximum braking rate capability of the target vehicle.
