Overtaking control method, vehicle-mounted terminal and computer readable storage medium

Abstract

The invention discloses an overtaking control method, a vehicle-mounted terminal and a computer readable storage medium. The method comprises the steps of reducing the current time distance gear of a vehicle after receiving a lane changing instruction of a driver, and obtaining and judging whether the real-time vehicle distance between the vehicle and a front vehicle and the real-time vehicle speed of the vehicle matches the current time distance gear of the vehicle or not; if not, taking the vehicle speed corresponding to the current vehicle distance under the current time distance gear as the first acceleration target of the vehicle to accelerate the vehicle; if the steering instruction is received, lowering the current time distance gear of the vehicle, and according to the current time distance gear, the steering angle and the vehicle speed, simulating the driving track of the vehicle and combining with the position of the front vehicle, and judging whether the vehicle switching is safe or not; further adjusting the speed of the vehicle and the distance between the vehicle and the front vehicle according to the judgment result; and after the vehicle is switched out of the front vehicle, restoring the current time distance gear to the cruise time distance gear, enabling the vehicle to run according to the target vehicle speed, and completing overtaking. According to the scheme, under the condition that acceleration safety is guaranteed, the risk of rear-end collision with a rear coming vehicle in the overtaking process is reduced.

Description

Technical field [0001] The present invention relates to the field of smart driving, in particular a self-adaptive cruise system over-vehicle speed and time-to-hour control method, a vehicle terminal, and a computer readable storage medium. Background technique [0002] Automatic cruise control is to allow the driver without operating the steering wheel, the clutch and the accelerator pedal can ensure that the car travels at a certain fixed pre-selected vehicle speed. When the car drives for a long time on the highway, open the cruise control switch, the system can automatically increase or decrease the opening of the engine's throttle according to the change of road travel resistance, so that the speed of the car must be kept, thus bringing a very good driving. Big convenient. However, when the vehicle encounters the need to overtake, the automatic cruise control system requires artificial intervention operations, and the overtaking program in the current adaptive cruise overtaki...
