Pedestrian protection system, method and vehicle including the system

Abstract

The invention discloses a pedestrian protection system for a vehicle, and the system comprises: a touch control switch which is disposed on a center console screen of the vehicle, and is configured tobe operated by a user in an available state so as to start a pedestrian protection function on the vehicle; a controller which is configured to obtain an on-off state of the touch control switch fromthe center console at a preset interval by means of a CAN bus technology and send the obtained on-off state to an algorithm module, wherein the on-off state is an on-off signal sent in the form of aCAN message; and the algorithm module configured to determine whether to activate a pedestrian protection function based on a switching state received from the controller, wherein the touch control switch maintains an available state only if at least one of the following conditions is satisfied: a current vehicle speed is less than or equal to a predetermined value, and is within a predetermined duration after an engine of the vehicle is ignited. The invention further discloses a corresponding pedestrian protection method and a vehicle comprising the pedestrian protection system.

Description

technical field [0001] The present application relates to the field of vehicle safety, and more specifically, the present application relates to a pedestrian protection system for a vehicle, a corresponding pedestrian protection method, and a vehicle including the pedestrian protection system. Background technique [0002] Nowadays, more and more vehicles are equipped with Pedestrian Protection (PPS) function, which can provide effective protection for pedestrians who are hit when traffic failure occurs. [0003] In the prior art, a hard-wired switch is mainly used to control the startup of the PPS. However, this method has the following problems: First, it requires special design and development of hard-wired switches and wiring harnesses, which increases the complexity of vehicle integrated wiring harnesses; second, it requires special design of the installation position of the switch, which requires the center console to open the mold, and the cost is high ; The third is...

Problems solved by technology

However, this method has the following problems: First, it requires special design and development of hard-wired switches and wiring harnesses, which increases the complexity of vehicle integrated wiring harnesses; second, it requires special design of the installation position of the switch, which requires the center console to open the mold, and the cost is high ; The third is that the driver needs to manually flip the physical switch, and the operating experience is poor

[0004] In addition, the trigger conditions that trigger the activation of the PPS function are too sensitive, which will cause the pedestrian protection system to be activated due to abnormal collisions, resulting in the need to replace system components and cause losses to car owners

For example, when the front of the car has a slight collision or when driving through some large bumpy roads, the pedestrian protection function may be activated accidentally / abnormally
