Problems solved by technology

[0003] The greater the mass, the greater the inertia of the object. When the vehicle load is too heavy, if the vehicle speed is too high, it is very easy to cause serious traffic accidents such as vehicle rollover and rear-end collision when encountering an emergency.
In order to avoid serious safety hazards caused by the driver slamming on the accelerator and driving at high speed due to driving skills / fatigue driving / malicious revenge when the vehicle is overloaded, the current vehicle is only equipped with an overspeed auxiliary alarm system, but the inventor found that the current vehicle overspeed The auxiliary alarm system only reminds the speed of the vehicle. After the threshold is set, it is immutable. It is not related to factors such as vehicle load and driving environment. It cannot avoid the driver's own subjective risk, and does not fully consider the balance between economic benefits and safe driving. question

Embodiment 1

[0031] This embodiment provides a vehicle self-adjusting speed limit method, such as figure 1 shown, including the following steps:

[0032] Step 1: Obtain environmental data information.

[0033] Specifically, the acquired environmental data information includes vehicle speed information, acceleration information, gradient information, and congestion degree information during the running process of the vehicle.

[0034] The vehicle speed information is obtained through the vehicle speed sensor installed in the vehicle, the acceleration information is obtained through the acceleration sensor installed in the vehicle, the slope information is obtained through the slope sensor installed in the vehicle, and the congestion level is obtained through the GPS positioning module.

[0035] Step 2: Determine the driving conditions of the vehicle according to the obtained environmental data information

[0036] In this embodiment, the vehicle driving conditions are divided into low-spe...

Embodiment 2

[0061] This embodiment provides a vehicle self-adjusting speed limit system, including:

[0062] Environmental data acquisition module: used to acquire environmental data information;

[0063] Vehicle driving condition determination module: used to determine the driving condition of the vehicle according to the obtained environmental data information;

[0064] Pedal voltage acquisition module: used to acquire the voltage signal of the vehicle load sensor and the voltage signal of the accelerator pedal sensor, and determine the pedal voltage in combination with the acquired vehicle driving conditions;

[0065] Control module: used to control the opening degree of the throttle valve according to the determined pedal voltage.

[0066] The pedal voltage acquisition module includes a comparison module and a pedal voltage output module. The comparison module is used to compare the pedal voltage corresponding to the voltage signal collected by the pressure sensor and the pedal volta...

Embodiment 3

[0068] This embodiment provides a vehicle. The vehicle is installed with a GPS positioning module, a vehicle speed sensor, an acceleration sensor, a gradient sensor, and an accelerator pedal sensor. Pressure sensors are installed at the four corners and at the center of the vehicle chassis. The pressure sensors are used to collect vehicle data. load information.

[0069] The vehicle also includes a controller. The controller adopts an ECU. The controller is respectively connected with the GPS positioning module, the vehicle speed sensor, the acceleration sensor and the pressure sensor signal. The controller is also connected with the throttle servo motor controller. Control the throttle valve servo motor action, and then control the throttle valve opening.

[0070] In this embodiment, the controller is used to execute the vehicle self-adjustment speed limiting method described in Embodiment 1, specifically:

[0071] During the driving process of the vehicle, the GPS positioni...

Abstract

The invention relates to a vehicle self-adjusting speed limiting method, a speed limiting system and a vehicle, belongs to the technical field of vehicle speed control, and solves the problem that current vehicle overspeed alarm does not consider the vehicle load and the driving environment, and the method comprises the following steps: obtaining environment data information; determining the working condition of vehicle driving according to the acquired environment data information; acquiring a voltage signal of a vehicle load sensor and a voltage signal of an accelerator pedal sensor, and determining pedal voltage in combination with the acquired vehicle driving working condition; by the adoption of the method, the vehicle load, the driving environment and other factors are considered in the vehicle speed limiting process, and the balance problem of economic benefits and safety is fully considered.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle self-adjusting speed limiting method, a speed limiting system and a vehicle. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] The greater the mass, the greater the inertia of the object. When the vehicle load is too large, if the vehicle speed is too high, in the event of an emergency, it is very easy to cause serious traffic accidents such as vehicle rollover and rear-end collision. In order to prevent the driver from stepping on the accelerator at high speed due to driving skills / fatigue driving / malicious retaliation and causing serious safety hazards when the vehicle is overloaded, the current vehicle is only equipped with an overspeed auxiliary alarm system. The auxiliary alarm system only reminds the speed of the vehicle. After setting the th...
