The invention relates to the field of automobile engines, in particular to an automobile engine hood and a control method thereof. The automobile engine hood comprises an engine hood assembly and an electromagnetic adjusting hinge assembly. The engine hood assembly comprises an engine hood and at least one pressure sensor arranged in the engine hood; the electromagnetic adjusting hinge assembly comprises a plurality of electromagnetic spring assemblies; the electromagnetic spring assembly comprises an electromagnetic spring support and a rotating hinge arranged on the electromagnetic spring support. The rotating hinge is used for supporting the engine hood; a spring controller is mounted on the electromagnetic spring support; the pressure sensor is electrically connected with the spring controller and used for sending a detected pressure signal to the spring controller so that the spring controller can adjust the rigidity of the electromagnetic spring support according to the pressure signal. The rigidity of the electromagnetic spring support is adjusted in time through the spring controller, the deformation space of the electromagnetic spring support and the contraction space of the engine cover are changed, and harm to pedestrians when a vehicle collides with the pedestrians is reduced.

    本发明涉及汽车发动机领域,尤其涉及一种汽车发动机罩及其控制方法。该汽车发动机罩包括发动机罩总成和电磁调节铰链总成;发动机罩总成包括发动机罩和设置在发动机罩中的至少一个压力传感器;电磁调节铰链总成包括若干电磁弹簧组件;电磁弹簧组件包括电磁弹簧支座以及设置在电磁弹簧支座上的转动铰链;转动铰链用于支撑发动机罩;电磁弹簧支座安装有弹簧控制器;压力传感器与弹簧控制器电性连接,用于将检测到的压力信号发送至弹簧控制器,以使弹簧控制器根据压力信号调节电磁弹簧支座的刚度。本发明通过弹簧控制器及时调节电磁弹簧支座的刚度,改变电磁弹簧支座的形变空间和发动机罩的收缩空间,减少车辆与行人碰撞时对行人的伤害。
