A brake controller of a machine can be configured to determine brake power associated with braking operations, such as operations to slow the machine or maintain a speed of the machine. The brake controller can allocate the brake power among systems such as a battery system, a resistive grid, auxiliary systems, a mechanical brake system, and/or other systems, based on a defined priority order of the systems. For example, the brake controller can prioritize using a regenerative brake system to charge a battery system during a braking operation up to a currently-available capacity of the battery system, and allocating any remaining brake power to a lower-priority system. The mechanical brake system can be the lowest-priority system, such that use of the mechanical brake system can be avoided unless an amount of brake power exceeds capacities of higher-priority systems to consume the brake power.

A technique controls an electric brake of a vehicle. The technique involves continuously providing power to the electric brake of the vehicle to continuously disengage the electric brake and allow the vehicle to move. The technique further involves, while power is continuously provided to the electric brake and the vehicle is moving, sensing a fault condition. The technique further involves, in response to sensing the fault condition, providing electric pulses to the electric brake in place of continuously providing power to the electric brake, the electric pulses having varying pulse timing that controls braking of the vehicle. Accordingly, the vehicle is able to provide a more consistent braking response regardless of variations in certain factors such as brake calibration and/or current wear, the current weight in the vehicle, the current temperature, etc.

The one or more processors determine a reference value based on the detection values by the sensors, by a determination method set in accordance with a control using data regarding the detection target, when the detection values by the sensors differ by the predetermined threshold value or more. The one or more processors carry out the control based on the reference value.

The present disclosure discloses a trailer braking control method and system based on an electric brake controller. A lateral displacement and speed of a vehicle are acquired first; whether the vehicle has Death Wobble and a degree of the Death Wobble are then determined according to the lateral displacement; if there is Death Wobble, a driving state of the vehicle is determined according to the speed; and finally, a set voltage is added based on a set output voltage according to the degree of the Death Wobble and the driving state, so as to brake the vehicle. The present disclosure avoids setting of a weight ratio in the prior art to prevent the phenomenon of Death Wobble, and can identify and prevent the phenomenon of Death Wobble of a trailer, thereby avoiding an overturning accident and ensuring the personal safety and the integrity of a vehicle.
