Abstract
The invention discloses an electric vehicle capable of cruising at a constant speed. The electric vehicle comprises a motor speed-regulating turning bar, a speed-regulating control circuit and a motor which are electrically connected in turn; the electric vehicle further comprises a constant-speed cruising control device which comprises a cruising control unit, a constant speed switch and a vehicle speed monitoring unit; the constant speed switch and the vehicle speed monitoring unit are respectively and electrically connected to the cruising control unit; and the cruising control unit is connected to the speed-regulating control circuit. In the electric vehicle, the constant-speed cruising control device is arranged on a traditional electric vehicle, thereby realizing a constant-speed cruising mode of the electric vehicle, avoiding forcibly holding the motor speed-regulating turning bar in a certain position by a driver, and promoting driving comfortableness. Furthermore, a brake action monitoring unit and a displacement sensor are respectively used for monitoring a brake action and a displacement of the motor speed-regulating turning bar, and when the brake action or the rotation of the motor speed-regulating turning bar exceeds a certain range, the electric vehicle automatically exits from the constant-speed cruising mode, thereby promoting the driving safety.
Description
Technical field
The present invention relates to a kind of battery-driven car, but relate 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 travelling, 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.
Summary of the invention
Technical matters to be solved by this invention 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 cruise of the present invention comprises the electric machine speed regulation handle, speed-regulating control circuit, the motor that are electrically connected in turn; 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 present invention, 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 another improvement project of the present invention, 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 present invention 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 are monitored through brake monitoring means and displacement pickup; When having monitored the rotation of brake or electric machine speed regulation handle above certain amplitude; Then withdraw from the cruise pattern automatically, improved drive safety.
Description of drawings
Fig. 1 is the structure and the functional block diagram of cruise control device of the present invention;
Fig. 2 is the control flow chart of cruise control device of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
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 turn; 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 present invention has increased the cruise control device that can make the battery-driven car cruise on its basis; Its structure and principle as shown in Figure 1, 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 vehicle speed signal 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 a core of the present invention, realizes cruise according to predefined programming control battery-driven car, and its workflow may further comprise the steps as shown in Figure 2:
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 cruising control of the present invention unit 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.
