    摘要: The present disclosure relates to an electrical parking control method and device, a readable storage medium and a computer device. The method includes that: when it is detected that a vehicle is in a self-piloting mode and a preset parking control condition is satisfied, a parking switching request message is generated, and sent to a VCU; a parking switching message fed back by the VCU is received, the parking switching message being a message generated when the VCU detects that a vehicle state is executable parking switching; a parking switching signal corresponding to the parking switching message is generated; and the parking switching signal is pushed to an external Electrical Park Brake (EPB) system, the parking switching signal being used to switch a state of the external EPB system, the state including a tightening state and a releasing state.

    摘要: A vehicle according to the present disclosure includes a brake device and an electronic control unit. The brake device is configured to change a front-rear distribution ratio of braking force with respect to front and rear wheels. The electronic control unit is configured to: control the brake device such that the front-rear distribution ratio is in accordance with a fixed distribution characteristic in which the front-rear distribution ratio is constant regardless of deceleration of the vehicle in at least a part of a first range being a required deceleration range lower than a lower limit value of the deceleration perceivable by a person in the vehicle; and control the brake device such that the front-rear distribution ratio is biased toward the rear wheel than that in the fixed distribution characteristic in a second range in which the deceleration is higher than that in the first range.

    摘要: 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.
