Intelligent control device for parking brake and auxiliary start

Abstract

The invention discloses an intelligent control device for parking brake and auxiliary start. The control device comprises a signal acquisition unit, an intelligent parking brake controller (11) and a parking actuating mechanism, wherein the parking actuating mechanism comprises a ratchet pawl button (14) for a parking brake handle, the parking brake handle (15), a ratchet pawl push rod (16) for the parking brake handle, a push rod (17) for an IPB ratchet pawl, a ratchet pawl (18) for the parking brake handle, a push rod return spring (19) for the ratchet pawl push rod, a ratchet wheel (20) for the parking brake handle, a metal guy cable (21),a guy cable stop block (22), a return spring (23) form the parking brake handle, an IPB motor bracket (24), an IPB ratchet wheel (26), a reel (27), aDC motor, a reducing mechanism (28) for the DC motor, the IPB ratchet pawl (29), a return spring (30) for the IPB ratchet pawl, a guy cable (31) for the IPB ratchet pawl, an electromagnet (32) and a lever (33) for the IPB ratchet pawl.

Description

Technical field [0001] The invention relates to an intelligent parking brake and auxiliary starting control device which can be applied to both manual gear and automatic gear models. Background technique [0002] With the development of automobile technology, people have higher and higher requirements for the comfort, safety, intelligence and humanization of automobiles. For the currently commonly used mechanical human parking brake system, it is also developing in the direction of electronic control. The service brake system developed by Bosch has a hill hold control function (HHC). For manual models equipped with this system, when starting on a hill, the accelerator pedal, clutch pedal and parking handle (or brake pedal) are not required to complete the start on the hill; for automatic models equipped with this system, when starting on a steep slope, There is no need to use the accelerator pedal and the parking handle to complete the hill start. When the car stops and the dr...

Problems solved by technology

[0003] Although the EPB system can realize functions such as automatic parking, auxiliary starting on slopes, emergency braking, and active braking, most EPB systems use the parking braking force implemented by the electromechanical brake, and the EPB button has no mechanical function. Connect the wheel cylinder, just an electronic switch

The assembly of electromechanical brakes will bring about a significant increase in cost, and some cars are equipped with such electromechanical brakes on all four wheels, which has caused most of the EPB to appear on the equipment list of luxury cars

Moreover, the electromechanical brake is arranged on the brake caliper body, the working environment is harsh, its reliability is affected, and the reliability of the electronic control system cannot be guaranteed when it fails.

In addition, the current EPB system requires the driver to press the EPB button to trigger the electric parking brake function. Although the physical burden is reduced, it is still a bit cumbersome, and the braking force does not change with the slope and the vehicle quality. adjust

Always apply the parking brake force under full load and suddenly release the brake force when starting, the car will run forward and may cause the engine to stall, reducing the starting time and driver comfort

Therefore, intelligent parking is not realized
