Embodiment Construction

[0047] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific implementation of the invention will now be described with reference to the accompanying drawings.

[0048] figure 1 It is a flowchart of a BOOST mode activation method for an electric vehicle provided by an embodiment of the present invention, and its specific steps are as follows:

[0049] Step 101: The electric vehicle is in the ready state of BOOST mode.

[0050] The preparation state of the electric vehicle in BOOST mode needs to meet the following conditions at the same time:

[0051] 1) The system failure of the electric vehicle is less than the preset level, such as: level 3;

[0052] 2) The allowable output power of the electric vehicle battery is greater than the preset output power threshold, such as: 40KW;

[0053]3) The motor temperature of the electric vehicle is lower than the preset first motor temperature threshold such as: 120 degr...

Abstract

The invention discloses a BOOST mode activating method and device of an electric automobile. The BOOST mode activating method of the electric automobile comprises the steps of detecting the followingactions that a gear shifter transmits an S gear signal, an accelerator pedal is stepped to a maximum opening 100% and a BOOST button is pushed down in sequence when the electric automobile is in a preparation state of a BOOST mode; judging whether requirements that a brake pedal is stepped down and a vehicle speed is zero are satisfied or not; if the requirements are satisfied, determining that the electric automobile enters an initial activated state of the BOOST mode and starting a first timer; before the first timer expires, detecting that the brake pedal is loosened; determining that the electric automobile enters a normal activated state of the BOOST mode; and triggering the electric automobile to formally enter the BOOST mode. According to the BOOST mode activating method of the electric automobile, reliable and safe BOOST mode activating operation is realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and device for activating a BOOST mode of an electric vehicle. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. [0003] The BOOST (furious) mode of electric vehicles is a working mode to realize the driver's speed experience. It requires the output torque of the front and rear motors to be above the peak torque, which involves personal safety, so the control strategy is very strict. [0004] The BOOST switch is on the steering wheel and is a trigger switch, which is easy to touch. When the BOOST switch is pressed, the vehicle enters the BOOST activation state. In this way, if the ...
