駐車防滑系統Parking anti-skid system

本創作係指一種控制車輛煞車系統及預警之方法，尤指一種在車輛幾近停止行進時，偵測車輛是否有滑動之潛在風險，若符合構成因素，則加以警示並輔助加壓煞車之主動式安全系統。This creation refers to a method of controlling the vehicle's braking system and early warning, especially a method of detecting whether the vehicle has a potential risk of sliding when the vehicle is almost stopped, and if the constituent factors are met, it will be warned and assisted in the initiative of the pressurized brake Security system.

早期的機械手煞車以及近期的電子手煞車，需駕駛在離車前手動拉起手煞車，車輛才會保有制動功能。The early mechanical hand brakes and the recent electronic hand brakes require the driver to manually pull the hand brake before leaving the car to maintain the braking function.

再者，現今新型車款上配備之自動駐車(Auto Hold)功能，其僅能在車輛煞停時自動進入駐車狀態，但無法避免因人為疏失，未採取使車輛產生制動力之相關措施，導致車輛因斜坡加速滑行造成的意外。因此，習知技術實有改進之必要。Furthermore, the Auto Hold function equipped on the current new models can only enter the parking state automatically when the vehicle is braked, but it is inevitable that due to human negligence, the vehicle has not taken relevant measures to generate braking force.
