The cruise control device is arranged on an existing electric vehicle, a cruise control mode of the electric vehicle is realized, accordingly, a driver does not need to keep the motor speed regulating rotary handle at a certain position forcefully, driving comfortableness is improved, a brake action monitoring unit and a displacement sensor are used for monitoring braking actions and displacement of the motor speed regulating rotary handle respectively, when the braking actions or rotation of the motor speed regulating rotary handle exceed a certain range, the electric vehicle exits from the cruise control mode automatically, and driving safety is enhanced.
Description
Technical field
The utility model relates to a kind of battery-driven car, but relates in particular to a kind of battery-driven car of cruise.
Background technology
Existing battery-driven car generally includes electric machine speed regulation handle, speed-regulating control circuit, motor, controls motor speed through driver's rotary electric machine speed control crank when going, and drives battery-driven car and quickens, slows down.When needs keep a certain speed, need the driver that the electric machine speed regulation handle is remained on certain location, the time causes driver's hand tired when long slightly easily.
The utility model content
The utility model technical matters to be solved is to overcome the deficiency of existing battery-driven car, but a kind of battery-driven car of cruise is provided.
But the battery-driven car of the cruise of the utility model comprises the electric machine speed regulation handle, speed-regulating control circuit, the motor that are electrically connected in order; This battery-driven car also comprises cruise control device, and said cruise control device comprises the cruising control unit, and the constant speed switch, the speed of a motor vehicle monitoring means that are electrically connected with the cruising control unit respectively; The cruising control unit is connected with said speed-regulating control circuit.
As an improvement project of the utility model, said cruise control device also comprises the brake monitoring means that is electrically connected with said cruising control unit.When the brake monitoring means monitors brake, send signal to the cruising control unit, the cruising control unit stops action, removes the cruise pattern, and the constant speed switch resets simultaneously.
As the another improvement project of the utility model, said cruise control device also comprises the displacement pickup that is electrically connected with said cruising control unit, and this displacement pickup is used to monitor the rotation displacement of said electric machine speed regulation handle.When the rotation displacement of electric machine speed regulation handle surpassed a certain value that is pre-set in the cruising control unit, the cruising control unit stopped action, removes the cruise pattern, and the constant speed switch resets simultaneously.
Preferably, said cruising control unit is the PID closed loop controller.
The utility model is through being provided with cruise control device on existing battery-driven car; Realized the cruise pattern of battery-driven car; Make the driver firmly the electric machine speed regulation handle remained on a certain position; Improved driver comfort, and further respectively brake, the displacement of electric machine speed regulation handle have been monitored, when having monitored the rotation of brake or electric machine speed regulation handle above certain amplitude through brake monitoring means and displacement pickup; Then withdraw from the cruise pattern automatically, improved drive safety.
Description of drawings
Fig. 1 is the structure and the functional block diagram of the cruise control device of the utility model;
Fig. 2 is the control flow chart of the cruise control device of the utility model.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model:
The battery-driven car of existing handle speed governing comprises electric machine speed regulation handle, speed-regulating control circuit, the motor that is electrically connected in order; Driver's rotary electric machine speed control crank; Speed-regulating control circuit is according to the position control storage battery of the electric machine speed regulation handle outgoing current to motor, thereby the control motor is with the different rotating speed drive wheels.The utility model has increased the cruise control device that can make the battery-driven car cruise on its basis; Its structure and principle are as shown in Figure 1, and this device comprises cruising control unit, constant speed switch, speed of a motor vehicle monitoring means, brake monitoring means and displacement pickup.Wherein the constant speed switch is used to open or cut out the cruise pattern of battery-driven car, and when the constant speed switch open, battery-driven car is in the cruise pattern; When the constant speed switch cut out, battery-driven car was removed the cruise pattern.Speed of a motor vehicle monitoring means is used to monitor the moving velocity of battery-driven car and GES is passed to the cruising control unit.The brake monitoring means is used to monitor the action of the brake system of battery-driven car, once monitor brake, then brake signal is passed to the cruising control unit, and the cruising control unit withdraws from the cruise pattern, recovers normal operation mode.Displacement pickup is used to monitor the rotation displacement of electric machine speed regulation handle; And displacement signal passed to the cruising control unit, the cruising control unit compares handle displacement and predefined value, when being worth greater than this; Then withdraw from the cruise pattern, recover normal operation mode.
The cruising control unit is the core of the utility model, realizes cruise according to predefined programming control battery-driven car, and its workflow is as shown in Figure 2, may further comprise the steps:
Whether step 1, detection constant speed switch are opened, and in this way, change step 2; As not, then keep the normal operation pattern;
Step 2, in order further to improve safety, safe vehicle speed range can be set in the cruising control unit, the present speed of a motor vehicle that real-time monitors like speed of a motor vehicle monitoring means exceeds this safe vehicle speed range, then keeps the normal operation pattern and control the constant speed switch to reset; As do not exceed, then get into the cruise pattern, change step 3;
Step 3, detect the brake monitoring means whether brake signal is arranged, in this way, then withdraw from the cruise pattern and control the constant speed switch and reset; As not, then change step 4;
Whether step 4, the rotation displacement that detects the electric machine speed regulation handle surpass the value that preliminary election is set, and in this way, then withdraw from the cruise pattern and control the constant speed switch and reset; As not, then change step 3.
In order to make under the cruise pattern, electric vehicle running speed is more stable, and the preferred PID closed loop controller in the cruising control unit of the utility model according to the real-time monitor signal of speed of a motor vehicle monitoring means, carries out closed loop control to the drive current of motor.
