Inventor:  Lalone, Duane R.

A braking system for a combined tractor-trailer assembly wherein a leading trailer is coupled to a towing tractor and a trailing trailer is coupled to the leading trailer. All of the wheels of the trailers are provided with brakes which may be applied and released in response to the operation of a brake control pedal operated by a driver in the tractor. The brakes also may be applied to the trailing trailer whenever the latter is parked. The brakes of the trailing trailer normally are ...

Inventor:  Koike, Masaki

A vehicle braking system includes an electric motor, an operating amount detector, a brake assist controller, a first braking device and a second braking device. The electric motor drives a driving wheel via a reduction ratio setting device. The first braking device makes the electric motor generate a first braking power under regenerative control. The second braking device generates a second braking power by actuating an actuator with an operating fluid to be pressurized through a hydraulic ...

Inventors:  Cabrera Carrillo, Juan Antonio; Castillo Aguilar, Juan Jesus; Simon Mata, Antonio; Ortiz Fernandez, Antonio; Garcia Vacas, Francisco; Guerra Fernandez, Antonio

The invention relates to an automobile braking system with grip prediction and continuous control of braking pressure, including a hydraulic circuit which regulates braking pressure by controlling a proportional pressure value (8) which maintains the necessary pressure on the brake piston (6) in order to perform suitable braking. Braking control is permanently performed by a control system capable of recognizing actual grip conditions at all times and of establishing the ideal ...
