The invention relates to the technical field of pure electric engineering vehicles, in particular to a drive-by-wire integrated electric drive system and an electric engineering vehicle. The drive-by-wire integrated electric drive system comprises at least two axles; an electric power assembly; a vehicle controller and an electric drive axle controller; a brake-by-wire system; a steer-by-wire system; the power takeoff is arranged on the electric power assembly; the hydraulic power-assisted braking system is connected with the power takeoff and matched with the brake to provide auxiliary braking force for the brake; and the hydraulic power-assisted steering system is connected with the power takeoff and matched with the steering gear to provide auxiliary steering force for the steering gear. The drive-by-wire integrated electric drive system takes electric steering and electric braking as main parts and hydraulic power assisting as auxiliary parts, double protection is achieved, steering force is provided through the hydraulic power-assisted steering system, and braking force is provided through the hydraulic power-assisted braking system; the problems that an existing electric engineering vehicle is insufficient in braking force and steering force and fails in braking and steering after high-voltage power failure are solved, and the personal safety and the vehicle safety are improved.

    本发明涉及纯电动工程车辆技术领域,具体涉及一种线控集成电驱系统及电动工程车辆。线控集成电驱系统包括:至少两个车桥;电动力总成;车辆控制器和电驱桥控制器;线控制动系统;线控转向系统;取力器,设置在电动力总成上;液压助力制动系统,与取力器连接且与制动器配合,以为制动器提供辅助制动力;液压助力转向系统,与取力器连接且与转向器配合,以为转向器提供辅助转向力。线控集成电驱系统以电转向和电制动为主,液压助力为辅,实现双重保护,通过液压助力转向系统提供转向力以及通过液压助力制动系统提供制动力,解决现有电动工程车辆制动力不足、转向力不足以及高压断电后制动失效、转向失效等问题,提高人身和车辆安全。
