A vehicle braking system includes: a master cylinder; a slave cylinder communicated with the master cylinder; a vehicle behavior stabilizer communicated with the slave cylinder; first and second master cut valves, each being a normally closed valve for opening and closing a fluid flow path between the master cylinder and the slave cylinder, for making hydraulic pressures in the slave cylinder and the vehicle behavior stabilizer work in a valve closing direction; a pressure sensor for detecting the hydraulic pressure in the vehicle behavior stabilizer; and a piston controller for advancing first and second slave pistons in the slave cylinder when the hydraulic pressure on the vehicle behavior stabilizer side, detected by the pressure sensor, exceeds a predetermined value, and returning the pistons at a predetermined timing.

A brake motor control device for control of an electric brake motor of an electromechanical braking device includes a connection unit configured to be connected to an auxiliary control unit for controlling the electric brake motor in an event of a fault of the brake motor control device. The electric brake motor is configured to displace a brake piston against a brake disc.

A powering pattern representing velocity of a vehicle at each position of a powering interval in a braking delay period between a timing at which the vehicle exceeds allowable velocity and a braking timing at which the vehicle starts to brake, and a coasting pattern representing velocity of the vehicle at each position of a coasting interval subsequent to the powering interval in the braking delay period are calculated after calculating a braking pattern representing velocity of the vehicle in a braking interval, which is a running interval subsequent to the coasting interval and which occurs between a position of the vehicle at the braking timing and a target position for controlling the vehicle to run at predetermined velocity or less, wherein an acceleration characteristic depending on velocity of the vehicle is used to calculate at least the powering pattern.

A system for braking a trailer towed by a tow vehicle. The system includes a signalling means for generating an electrical signal based on an action applied by a driver to a brake operating unit.

Systems and methods are described for coordinating and controlling vehicles, for example heavy trucks, to follow closely to behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicle sensors to monitor and control, for example, gross vehicle weight, axle loads, and stopping distance. In some aspects, two vehicles can determine information associated with their gross weight and axle load, and apply that information to assist with determining a bounding box indicating which vehicle will take longer to stop. Based on which vehicle will take longer to stop, an order of vehicles in a potential platoon is determined.

A system and method for braking a tractor-trailer assembly is provided. The method includes generating a tractor brake pressure for application to a tractor brake for braking a tractor wheel, determining a tractor brake rate based on one or more of the generated tractor brake pressure, one or more parameters of the tractor brake, one or more parameters of the tractor wheel, one or more parameters of a final drive, and a mass of the tractor, and determining a trailer brake pressure applied to a trailer brake of a trailer wheel of a trailer, based on the determined tractor brake rate.
