Embodiment Construction

[0036] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] see Figure 1 to Figure 2 As shown, this embodiment discloses a vehicle keyless start method, the steps include:

[0038] (S1) Press the start switch to check whether the key is in the car. If so, the keyless controller switches the vehicle power from OFF to ACC or ON, and the keyless controller sets the key-finding flag Flag to 1; Otherwise, the process of not powering on the vehicle ends.

[0039] (S2) Detect whether the state of the car door or the state of the window or the state of the engine changes, if so, the keyless controller sets the flag bit Flag from 1 to 0; otherwise, the flag bit Flag remains 1;

[0040] (S3) Step on the brake or step on the clutch and press the start switch at the same time, the keyless controller detects the flag status of the key finding flag; if Flag=1, execute step (S4); if Flag=0, execute step (...

Abstract

The invention discloses a vehicle keyless starting method and system and a vehicle. The method comprises the steps that a starting switch is pressed, whether a key is in the vehicle or not is detected, if so, a keyless controller switches a whole vehicle power source from an OFF gear to an ACC gear or an ON gear, and the keyless controller sets a key finding flag bit Flag to be 1; whether a vehicle door state or a vehicle window state or an engine state is changed or not is detected, and if so, a key finding flag bit Flag is set from 1 to 0 by the keyless controller; otherwise, the key finding flag bit Flag is kept to be 1; when a brake or a clutch is stepped on and a starting switch is pressed at the same time, the keyless controller detects the state of a key finding flag bit Flag; if Flag is equal to 1, the keyless controller directly sends a starting request signal to an engine control unit (ECU), and the vehicle is started. According to the method, the vehicle function and experience are not affected when interference occurs after power-on, the vehicle use trouble is avoided to a certain extent, and the driving experience is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a vehicle keyless starting method, system and vehicle. Background technique [0002] With the development of automobile intelligence, the keyless control system that has existed for more than ten years is also facing certain challenges in terms of experience. For example, ①The user installs a driving recorder and takes power from the cigarette lighter. When the vehicle is started, the power at the cigarette lighter interferes with the key, causing the instrument to prompt that the key is not detected, which affects the driving experience; After powering on and restarting, there may also be a problem that it cannot be started; ② For vehicles with wireless charging function, after powering on and restarting, the mobile phone will repeatedly prompt to charge. The above problems have become urgent problems to be solved in the current era of higher and higher requirem...
