A foot operable controller for a surgical instrument having a main foot pedal assembly providing either proportional or linear control signals when moved laterally and in a vertical direction. Friction between an operator's foot and the foot pedal is minimized by a foot pad having a rotating heel plate. A neutral zone between left and right control positions of the foot pedal enables the operator to move his foot freely without changing control settings. Vertical displacement of the foot pedal is indicated by a plurality of mechanical detents during both upward and downward travel. Changing detent resistance alerts the operator to the vertical position of the foot pedal, indicating that further vertical displacement will change an instrument control signal corresponding to the new foot pedal position, thus providing sensory feedback to the operator indicating a change in the functional mode when the foot pedal is moved.

A brake apparatus for a vehicle generally sets an upper limit value of regenerative braking force to the maximum value of the regenerative braking force which can be generated at the present. In the case of a front-wheel-drive vehicle, the total braking force, the sum of front-wheel braking force (front-wheel hydraulic braking force+regenerative braking force) and rear-wheel braking force (rear-wheel hydraulic braking force), is rendered coincident with a target braking force corresponding to a brake pedal depressing force, and the regenerative braking force is set to a largest possible value equal to or less than the upper limit value. As a result, the regenerative braking force can be larger than front-wheel-side target distribution braking force. The upper limit value is decreased from the maximum value by an amount corresponding to the degree of easiness of occurrence of a locking tendency at the driven wheels (front wheels).
