A braking control system is provided comprising a first brake controller configured to receive a first brake demand generated by a first brake pedal of a vehicle; and a second brake controller configured to receive a second brake demand generated by a second brake pedal of the vehicle. The first brake controller is further configured to provide the first brake demand to the second brake controller, and the second brake controller is further configured to determine which of the first brake demand and the second brake demand is greater. At least one of the first and second brake controllers is further configured to cause a braking system of the vehicle to decelerate the vehicle according to the greater brake demand. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

Braking control system and method for arbitrating brake demands from a plurality of foot brake modules

In one embodiment, a foot brake module is provided comprising: a sensor configured to generate a brake demand; a first transceiver configured to receive a brake demand generated by a second foot brake module of a vehicle; a processor configured to determine which of the brake demand generated by the second foot brake module and the brake demand generated by the sensor is greater; and a second transceiver configured to send the greater brake demand to a brake controller of the vehicle. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

A braking system with redundant trailer communication is provided. In one embodiment, a braking control system for a tractor-trailer comprises a primary brake controller in a tractor configured to communicate with a trailer brake controller in a trailer via a first communication channel, and a redundant brake controller in the tractor configured to communicate with the trailer brake controller via a second communication channel. The primary brake controller is further configured to serve as a master brake controller for the trailer and communicate with an automated driving computer in the tractor. The redundant brake controller is further configured to take over as the master brake controller in response to determining that the primary brake controller can no longer serve as the master brake controller.

Braking system with redundant trailer communication

A braking control apparatus for use in an associated multiple-steer vehicle having first and second steerable axles and a plurality of drive axles effects axle-by-axle braking control of steerable wheel brakes of the steerable axles and wheel-by-wheel braking control of drive wheel brakes of the drive axles, respectively, to perform a braking operation in the associated multiple-steer vehicle. The axle-by-axle braking control of the steerable wheel brakes and the wheel-by-wheel braking control of the drive wheel brakes are simultaneously effected to decelerate the vehicle using both the steerable and drive wheel brakes so that the ability to steer the vehicle is not adversely affected should one or more of the steerable wheel brakes on any of the steerable axles experience slippage, skidding, or lockup during the braking or deceleration.

A brake demand arbitrating device is provided comprising: a first transceiver configured to receive a first brake demand generated by a first brake pedal of a vehicle; a second transceiver configured to receive a second brake demand generated by a second brake pedal of the vehicle; a processor configured to determine which of the first brake demand and the second brake demand is greater; and a third transceiver configured to send the greater brake demand to a brake controller of the vehicle. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
