Embodiment 1

[0038] refer to figure 1 and figure 2 , a dual-clutch vehicle escape method, the method is applied to a vehicle, the vehicle includes: a first clutch and a second clutch; the method includes:

[0039] Step S1: receiving the basic parameters output by the vehicle and the preset conditions corresponding to the basic parameters.

[0040] Wherein, each basic parameter includes: the rotational speed difference of the driving wheels, the gear position, the throttle and the temperature of the second clutch.

[0041] The preset conditions include: a preset first speed difference threshold, a preset gear position, a preset throttle threshold, and a preset first temperature threshold. For example, the preset first rotational speed difference threshold may be 200 rpm; the preset gear position may be D gear; the preset accelerator threshold may be 20% of the accelerator pedal opening; the preset first temperature threshold may be 200°C.

[0042] In this step, the preset condition is a...

Embodiment 2

[0066] refer to Figure 4 , based on the same inventive concept, another embodiment of the present application provides a dual-clutch vehicle escape device, the device is applied to a vehicle, and the vehicle includes: a first clutch and a second clutch; the device includes:

[0067] a data receiving unit, configured to receive the basic parameters output by the vehicle and the preset conditions corresponding to the basic parameters;

[0068] a judging unit, judging whether each of the basic parameters meets the corresponding preset conditions;

[0069] a control unit; if so, controlling the first clutch to transmit the first torque value of the engine, and at the same time combining the second gear synchronizer to output the first torque value of the engine to the wheel end;

[0070] Wherein, when the first clutch is controlled to transmit the first torque value of the engine, the first clutch accelerates the flow of cooling fluid to speed up the cooling of the second clutch...

Abstract

The embodiment of the invention provides a double-clutch vehicle escape method, device and system and a vehicle, and belongs to the technical field of automobiles. The method is applied to a vehicle, and the vehicle comprises a first clutch and a second clutch. The method comprises the steps that basic parameters output by the vehicle and preset conditions corresponding to the basic parameters are received; judging whether the basic parameters conform to corresponding preset conditions or not; if yes, the first clutch is controlled to transmit a first torque value of an engine, and meanwhile, a second-gear synchronizer is combined to output the first torque value of the engine to a wheel end; and under the condition that the first clutch transmits the first torque value of the engine, the first clutch accelerates flowing of cooling liquid so as to accelerate cooling of the second clutch. By means of the double-clutch vehicle escape method, the second clutch can be cooled on the premise that the vehicle is helped to escape.

Description

technical field [0001] The embodiments of the present application relate to the technical field of automobiles, and in particular, relate to a dual-clutch vehicle escape method, device, system and vehicle. Background technique [0002] A clutch is an automotive component used to temporarily separate or gradually engage the engine and the transmission. It can cut off the power input from the engine to the transmission; it can also transmit the power input from the engine to the transmission. [0003] In the prior art, when the vehicle is started on a road with relatively low adhesion, for example, on a gravel road, the vehicle tends to slip. When the vehicle is slipping, the clutch temperature will rise rapidly. If the vehicle continues to start when the clutch temperature rises, it will easily cause clutch ablation. Therefore, in order to prevent the clutch from ablation under high temperature conditions, the output torque of the engine is usually reduced to protect the clu...
