Problems solved by technology

[0008] The purpose of the present invention is to provide a fuel-powered vehicle that can overcome the problems that the existing vehicle auxiliary drive methods cannot significantly reduce the fuel consumption of the engine and that the braking energy cannot be directly used to drive the vehicle on the fuel vehicle. A vehicle drive assist method in which the braking energy during driving is directly absorbed, stored and used to drive the vehicle to start

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] A kind of vehicle driving aid method of the present invention, it adopts such as figure 1 The drive-assisted mechanism shown specifically includes the following steps:

[0037] a. When the brake pedal is depressed and the vehicle starts to brake, a second clutch 32 connected to the output of the transmission 2 and associated with the brake pedal is engaged. Under the inertia of the vehicle, the wheels drag the transmission in the opposite direction, and the transmission The output end drives a power storage coil spring 8 to wind and store energy through the second clutch and a power storage transmission system;

[0038] b. When the brake pedal is released to end braking, the second clutch associated with the brake pedal is disengaged,

[0039] If the vehicle is in the state of decelerating at this time, the energy storage coil spring r...

Abstract

The invention discloses a vehicle auxiliary drive method. When a brake pedal is hit, a second clutch connected to an output end of a transmission connects, wheels reversely drag the transmission, and the transmission drives an accumulation coil spring to wind for energy accumulation; when brake is finished, the second clutch disconnects, if a vehicle is in a deceleration state, the accumulation coil spring returns to release elastic deformation energy and transmits power to a differential mechanism to drive the vehicle in an auxiliary manner, and if the vehicle is in a stop state, a controller locks the accumulation coil spring according to a signal control locking device of a vehicle speed sensor, when the vehicle starts again, the controller unlocks the locking device, the accumulation coil spring returns to release elastic deformation energy to aid an engine so as to drive the vehicle to accelerate. By the method, brake energy can be fully absorbed, stored and used for driving vehicle starting, starting performance of the vehicle can be improved favorably, and oil consumption and emission can be lowered evidently.

Description

[0001] technical field [0002] The invention relates to a vehicle auxiliary driving technology, in particular to a vehicle auxiliary driving method which can store vehicle braking energy and use it for auxiliary driving when starting. [0003] Background technique [0004] Vehicles need frequent braking and starting during driving. Existing vehicle braking is usually achieved by hydraulically driven brake calipers clamping brake pads that are coaxial with the wheel shaft. Since the brakes rely on brake calipers The friction between the brake disc and the brake disc is completed. Therefore, frequent braking will cause the wear of the brake calipers and brake discs and other braking devices, which need to be replaced after a period of use, and the inertial kinetic energy of the vehicle during the braking process is lost Convert it into heat energy and waste it in vain. In addition, when the vehicle is restarted after braking, it is difficult to control the throttle. If the ...
