Problems solved by technology

[0002] Existing vehicles often have a short distance between the front and rear vehicles during driving, which can easily cause rear-end collision accidents; in addition, when the front vehicle brakes lightly or abruptly during driving, it is often impossible to distinguish the rear vehicles, and the rear vehicles only It can judge the state of the vehicle in front and control its own speed through the change of sight distance, but when the speed is fast, this judgment is often not timely, which will lead to rear-end collision

Embodiment 2

[0029] The navigation method of the vehicle navigation system includes a gyroscope used to obtain the driving direction of the vehicle, a GPS module used to obtain the driving position of the vehicle, and a data storage device used to store map data. When the brake lights are on, the processor module sends a brake light control signal to the vehicle controller, and the vehicle controller controls the brake lights of the vehicle to be turned on.

Embodiment 3

[0031] Such as Figure 2-8 As shown, the vehicle for which the above-mentioned navigation system is applied in the present invention includes a gasoline engine, and the gasoline engine includes a fuel injector, and the fuel injector includes: a valve body 1, a plunger cavity 2, a conical cavity 3, a valve seat 4, and a Port 5, liquid inlet hole 6, control tank 7, controller 8, liquid injection port 9, drainage channel 10, plunger 11, upper plunger 12, lower plunger 13, cone 14, valve needle 15.

[0032] The top of the cylindrical valve body 1 is provided with a cylindrical control groove 7, and the lower end of the control groove 7 is provided with a cylindrical plunger chamber 2, the plunger chamber 2 communicates with the control groove 7, and the bottom end of the plunger chamber 2 There is a tapered chamber 3 with the tip pointing down, and the bottom end of the tapered chamber 3 is provided with a valve seat 4 with a hemispherical inner wall. The control groove 7, the plu...

Abstract

The invention discloses a vehicle-mounted navigation system, a navigation method and a vehicle with the vehicle-mounted navigation system. The vehicle-mounted navigation system comprises a navigation device, a camera located on the vehicle and used for acquiring conditions ahead of the vehicle and a vehicle controller. The vehicle comprises the vehicle-mounted navigation system and a gasoline engine with an oil injection tube. Through the vehicle-mounted navigation system and the navigation method, chain rear-end collision and speeding can be avoided in the running process of the vehicle, and reduction of the oil injection efficiency of an oil injector can be avoided.

Description

technical field [0001] The invention relates to the fields of navigation and vehicles, in particular to a vehicle navigation system, a navigation method and a vehicle using the vehicle navigation system. Background technique [0002] Existing vehicles often have a short distance between the front and rear vehicles during driving, which can easily cause rear-end collision accidents; in addition, when the front vehicle brakes lightly or abruptly during driving, it is often impossible to distinguish the rear vehicles, and the rear vehicles only It can judge the state of the vehicle in front and control its own speed through the change of sight distance, but when the speed is fast, this judgment is often not timely, which will lead to rear-end collision. After a rear-end collision, a series of rear-end collisions will occur immediately. [0003] How to avoid serial rear-end collisions and speeding is a technical problem to be solved in this area. Contents of the invention ...
