The present disclosure provides an emergency braking system, an emergency braking method and a semitrailer, capable of improving the braking effect of the vehicle, thereby achieving improved safety for the vehicle. The system includes: a sensor component configured to collect sensed information on an environment where a semitrailer is located; and a braking controller configured to determine whether there is a risk of collision for the semitrailer based on the sensed information, and if so, calculate a maximum adhesive force that can be provided by a road surface the semitrailer is currently on, determine a first braking pressure corresponding to each wheel based on the maximum adhesive force and axle load information, and transmit to a braking system a first braking instruction carrying the first braking pressure for each wheel.

A vehicle control system comprising an electronic processor, the processor comprising an input port for receiving data from a loading apparatus concerning at least one of the weight, dimensions, volume, or location of a load placed or to be placed by the loading equipment into or onto an associated vehicle in which the vehicle control system is fitted, and is programmed to use the data received from the loading apparatus to make control adjustments such that the associated vehicle maintains stability.

The invention relates to a method and an arrangement for controlling a vehicle (100) during a downhill start. The vehicle comprises a service brake (131a, 131b; 132a, 132b; 33a, 133b), an engine (119) and a transmission (120) being arranged between the engine and at least one driven axle (123), wherein the service brakes, the engine and the transmission are controlled by an electronic control unit (140). The method involves registering that the vehicle is located on a downhill gradient; registering an action from the driver, indicating a request to start the vehicle; controlling the service brake to maintain the vehicle stationary during a predetermined time after the request before initiating a controlled service brake release; controlling a gradual release of the service brake in response to at least one detected first vehicle operating parameter; and releasing the service brake when detecting that a predetermined threshold for at least one second vehicle operating parameter has been attained.

In various example embodiments, a system and method for determining a trailer brake gain signal for trailer brakes on a trailer being towed by a vehicle, and applying brakes to the trailer is disclosed. A method includes: providing predetermined calibration settings relating motor drive force to motor speed for a vehicle travelling at various speeds and providing accelerometer data. The method then determines that one or more vehicle performance parameters fall within threshold ranges and then determines both the vehicle weight and the trailer weight. The brake gain signal is determined based on the ratio of the current trailer weight and the original trailer weight. The brake gain signal is then transmitted to a trailer brake controller that applies trailer brakes according to the brake gain signal.

Trailer brake gain in a towing configuration of a tow vehicle and a trailer is determined by providing, to a processor, trailer wheel rotation information. The processor provides trailer brake control signals at a plurality of different evaluation trailer brake gains. The processor determines the trailer brake gain based upon the trailer wheel rotation information corresponding to the plurality of different evaluation trailer brake gains.

An agricultural train assembly having a tractor and at least one implement coupled to the tractor through a tongue. The assembly has a tractor braking system that selectively applies tractor brakes, an implement braking system that selectively applies implement brakes, a controller that selectively applies the implement braking system, a sensor that communicates with the controller to identify a push force applied to the tongue, the push force being the amount of force applied by the at least one implement towards the tractor. Wherein, the controller communicates with the sensor to identify the push force and compares the push force to a push threshold and when the push force is greater than the push threshold, the controller instructs the implement braking system to apply a burst braking procedure.

A system for braking a trailer pulled by a vehicle. A trailer braking system is provided on a trailer. An electrically actuated motor drives a worm screw against a worm gear. The worm gear drives a brake actuator to push brake pads into a rotor coupled a wheel on the trailer. A wheel speed monitor reduces braking force of the trailer braking system in response to a predetermined change in wheel speed. An anti-lock braking system reduces trailer wheel skid under braking. Multiple trailer braking systems can be applied to multiple wheels on the trailer to provide more or less braking.

Techniques are described for determining weight distribution of a vehicle. A method of performing autonomous driving operation includes receiving two sets of values from two sets of sensors, where a first set of sensors measure weights or pressures applied on axles of a vehicle, and where a second set of sensors measure pressures in tires of the vehicle. The method performs an error detection and removal operation to remove or filter out any erroneous values from the two sets of values to obtain two sets of filtered values. The method determines one or more values that describe a weight or pressure applied on the axle to obtain the weight distribution of the vehicle based on the first set of filtered values or the second set of filtered values. Based on the obtained weight distribution of the vehicle, the method can determine a driving operation of the vehicle.

A platooning controller, a vehicle system including the same, and a method thereof perform braking control based on a hitch angle. The platooning controller includes a processor that controls platooning of one or more vehicles, each with a trailer, and includes a storage storing information for controlling the platooning. The processor controls a host vehicle such that a hitch angle of the host vehicle with the trailer meets a predetermined reference angle, when it is necessary to perform braking control, and controls the host vehicle to perform the braking control.

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.
