电子机械式停车制动推荐
Service Training, VK-21 03.2005 * The driver can use an emergency delay for vehicles with conventional handbrake via handbrake lever e.g. in the event of a faulty brake pedal. A significantly improved emergency brake function has been implemented, because vehicle delay is carried out by an active brake pressure increase at all 4 wheels. The result is a safe – and depending on the driving situation ABS/ESP-controlled – vehicle delay of 6 m/s2. If button E538 is pressed at speeds above 7 km/h, the delay request is implemented by the communication of the control unit of the electromechanical parking brake. At the same time the engines drive moment is hidden and supporting functions such as CCS or ACC are disabled. If the button is released, the delay is cancelled immediately. 当制动踏板有故障时,对于所有的传统手刹车的车辆驾驶员可以通过操纵手刹车而是车辆应急减速。而在这里,值得注意的是应急制动功能效果提高了,因为车辆减速是通过施加在四个车轮上的主动制动力增加实现的。其结果是安全的-依靠ABS/ESP控制条件-车辆的减速度为6 m/s2。 如果车速大于7 km/h,减速请求由驻车制动控制单元通过通信发出。同时发动机驱动扭矩将被忽视,其所支持的CCS or ACC 功能也会终止,如果放开按钮,车辆减速会立即取消。 Service Training, VK-21 03.2005 * The dynamic starting assistant enables the driver to start the parked vehicle without jerking or jolting. The driver therefore no longer needs to release the parking brake in stages e.g. while at the same time having to operate clutch and accelerator while driving the car. The electromechanical parking brake is released on a fully automatic basis as soon as the driver starts the vehicle and if the advancing moment of the vehicle is above the descending force calculated by the control unit for the electromechanical parking brake. The information about the applied gear is available on the CAN in vehicles with automatic gearbox. For vehicles with manual gearbox, the clutch actuation sequences must also be analyzed. For this purpose, a special clutch sensor (Hall principle) was integrated into the existing clutch sensor module. Preqrequisite for activating the DAA is the drivers presence in the vehicle that is ensured by a safety belt fastene
