Embodiment 1

[0049] refer to figure 1 , the engine power control system of the vehicle described in this embodiment includes:

[0050] a load sensor 1 for detecting the load of the vehicle;

[0051] an angle sensor 2 for detecting the motion state of the vehicle;

[0052] An ECU 3 for adjusting the power of the engine according to the load and the motion state.

[0053] Among them, the load sensor 1 is also used to detect whether the road that the vehicle travels on is flat; the angle sensor 2 is used to detect whether the vehicle is in an uphill state or a downhill state; and the power is divided into full load power and medium load from large to small. Power, light load power and no-load power, eg when the vehicle is fully loaded, corresponds to full load power.

[0054] refer to figure 2 , a vehicle engine power control method, comprising the following steps:

[0055] step S 1 , detect the load of the vehicle and the motion state of the vehicle;

[0056] step S 2 , Adjust the p...

Embodiment 2

[0058] The basic principle of embodiment 2 is the same as that of embodiment 1, except that:

[0059] The engine power control system further includes an instruction receiving device for receiving an instruction input by a user;

[0060] The ECU is used to adjust the power of the engine according to this command.

[0061] In this embodiment, the ECU automatically selects an appropriate power mode according to the load condition of the vehicle and the operating road conditions obtained by the vehicle load sensor and the angle sensor, so as to achieve the purpose of economical operation.

[0062] Moreover, the ECU is used to monitor the state of the command receiving device in real time, adjust the power of the engine according to the command when the command receiving device receives the user's command, and adjust the power of the engine according to the load and the motion state when not receiving the user's command Adjust the power of the engine.

[0063] For users who are fa...

Embodiment 3

[0068] The basic principle of Embodiment 3 is exactly the same as that of Embodiment 2, and the following refers to image 3 , to further illustrate the technical solution of the present invention with a specific application example.

[0069] In principle, Embodiment 3 is exactly the same as Embodiment 2, in addition to automatic power adjustment, manual power switching is also supported. The default is automatic mode, and the initial is the maximum power mode. Two calibration data sections are opened in the ECU to store the vehicle empty weight value and the vehicle full load weight value respectively.

[0070] The ECU directly drives two manual switches, namely the ECO1 switch and the ECO2 switch. These two manual switches are used for manually activating the economical operation function. When the two switches are turned off and disconnected, four combinations can be obtained corresponding to the four power modes, that is, the ECO1 switch and the ECO2 switch are fully off ...

Abstract

The invention discloses an engine power control system and method. The engine power control system comprises a load sensor for detecting the load of a vehicle, an angle sensor for detecting the motion state of the vehicle, and an ECU (Engine Control Unit) for adjusting power of the engine according to the load and the motion state. With utilization of the sensors, the engine can automatically recognize the load of the vehicle and select the optimally economic running mode on the premise of ensuring the driving force, so as to practically meet the requirements on fuel economy for users; in addition, a manual adjustment manner can be adopted in the meantime, and the system can recognize commands inputted by a user to adjust the power. Therefore, the engine power control system is more flexible in power adjustment, and meanwhile ensures that the engine runs at the optimal power without lightening the weight of the vehicle or sacrificing the security of driving.

Description

technical field [0001] The invention relates to an engine power control system and method, in particular to an engine power control system and method for automatically adjusting power. Background technique [0002] In the actual work of the car, there may be a full load state, a medium load state, a light load state, or an no-load state. [0003] It is a waste to let the engine work in a power mode to cope with the above four working states, and its fuel economy cannot be satisfied by the user. [0004] In recent years, oil prices have been soaring, and the majority of users are increasingly calling for fuel economy. [0005] In order to meet the needs of users, many manufacturers have made the following improvements to the vehicle in recent years: [0006] 1) Reduce the weight of the whole vehicle and improve the effective power. [0007] 2) The engine ECU (electronic control unit) adds a multi-power mode. If there are ECUs with 380 horsepower, 350 horsepower, 325 horse...
