Description

Technical field

[0001] The invention relates to an automobile safe driving device, in particular to an active safe driving device of an automobile ABS / ASR / ACC integrated system. The automobile ABS (Anti-lock Braking System) device refers to the automobile brake anti-lock device, the automobile ASR (Automatic Slip Regulation) device refers to the automobile drive anti-skid device, and the automobile ACC device (Adaptive Cruise Control) refers to the vehicle speed adaptive control device. , Automotive ABS / ASR / ACC integrated system refers to the integrated system that the car has ABS, ASR and ACC functions at the same time and organically merges. Background technique

[0002] At present, in the world, the technical status of safe driving devices based on automotive ABS / ASR / ACC integrated systems is zero.

[0003] The published content of Yu Zhisheng's textbook Automobile Theory 3rd Edition published by the Machinery Industry Press in February 2003, and the contents published on page...

Embodiment Construction

[0028] In Figure 1 and Figure 2, when the driver judges that the vehicle needs to be decelerated until it stops, when the ABS control mode is applied, the driver depresses the brake pedal 1, and the vacuum booster 2 amplifies the brake pedal force and pushes the brake The movement of the piston in the master cylinder 3 causes the brake master cylinder 3 to generate pressure oil. The brake master cylinder 3 is output to the ABS through the ASR normally open oil inlet solenoid valve 5 and the ACC normally open oil inlet solenoid valve 43 through the double pipeline. The pressure regulator 42 and the ABS pressure regulator 42 are divided into four brakes which are respectively output to the four wheels. One way supplies pressure oil to the left front wheel brake 60 through the left front wheel oil inlet solenoid valve 7, and the other way supplies oil through the right front wheel. The solenoid valve 16 supplies pressure oil to the right front wheel brake 48, one way supplies pressur...
