Drive-by-wire chassis controller, electric vehicle braking and recharging control system and control method thereof

The invention provides a drive-by-wire chassis controller, an electric vehicle brake recharging control system and a control method thereof.The drive-by-wire chassis controller comprises a judgment module configured to judge whether an electric vehicle is in a brake state or not, and a calculation module configured to calculate the brake recharging of the electric vehicle when the electric vehicle is in the brake state. A controller configured to calculate a maximum brake recharge negative torque based on the first parameter, calculate a ratio of a mechanical brake operation to a brake recharge operation based on the brake command, a change rate of the brake command, and a vehicle speed in a state where the maximum brake recharge negative torque is non-zero, and obtain an analysis result; and the sending module is configured to send a mechanical brake control command and a brake recharging control command based on the analysis result. According to the mode, after the drive-by-wire chassis controller receives
