Abstract
The present invention relates to a multifunctional electric steering gear, a steering servo motor and the control method for wheel-type vehicles, which features use of microcomputer system.
Description
The present invention relates to a kind of wheeled car multifunctional electric steering gear of that constitute by microcomputer system, electromechanical integration and turn to the control method of servomotor torque constant.
It is by artificial steering wheel rotation that common wheeled car turns to, rotating torque is delivered to steering box through deflecting bar, after the mechanical drive deceleration break-in in the steering box, from steering box output shaft output steering torque, driving turns to longitudinal and transverse pull bar, finishes the steering operation of wheel.Used power when turning in order to alleviate chaufeur, many vehicles also are equipped with hydraulic pressure or electric turning booster device.
When the function of steering swivel system being proposed higher the requirement; as in the angle that requires to adjust quickly and accurately the car opinion under the situation of the road surface of complexity, introduce the automatic guidance parameter after to the real-time automatic guidance of route or travel by vehicle, based on the various automatic protectiveness correction of safety control and restriction, remote manipulation, automatic steering etc., traditional steering swivel system is just not competent.
The objective of the invention is, transmission and control method with digital signal replace traditional mechanical drive control method, overcome mechanical drive and be difficult to introduce the deficiency of interfering controlled variable, the intervention of the steering swivel system adding automatic guidance parameter of vehicle is realized easily.
The present invention is made up of four parts: steering wheel assembly, controller, turn to servomotor torque constant, traditional mechanical steering box.There is not mechanical connection between bearing circle and the mechanical steering machine.
Steering wheel assembly comprises: bearing circle, torque sensor, rotary angle transmitter, steering torque feedback electrical motor.
Controller is a Single Chip Microcomputer (SCM) system, and the director data of receiving sensor and higher controller sends turning to the control command of servomotor torque constant and wheel steering moment feedback electrical motor.
Steer motor is a servomotor torque constant, is installed together with traditional mechanical steering machine, by the deflecting bar of the output shaft direct drive steering box of servomotor torque constant, finishes turning to function.
Together delivered to controller by the data of steering torque sensor output, the instruction that data, telecommand or other higher controllers of other state sensor outputs send, after corresponding program deciphering, export a control instruction corresponding, control turns to the running of servomotor torque constant and the counter torque of steering torque feedback electrical motor, reaches the purpose that control turned to and fed back to chaufeur cornering resistance.
The action instruction of just angle and the torque sensor of bearing circle being sent or turning right at when operation chaufeur steering wheel rotation, the output of sensor is one of foundation of controller control servomotor torque constant, and to be subjected to the output command intervention of other state sensor data and higher controller when specifically carrying out, finally turn to the operative condition of servomotor torque constant will depend on output command after program is judged corresponding conditions.Therefore, the total effect that turns to is artificial and the common decision of program.Improper or faulty operation artificial under certain condition can be corrected or cancel, and the condition judgment program that configures in advance can provide best output command.Steering swivel system can also be fully operational in the driverless operation operating mode, and the steering order control that this moment, controller sent according to telecommand or personal vehicle system turns to the operation of servomotor torque constant, realizes that remote control turns to or automatic steering.
The present invention can replace common steering swivel system and steering boost system, has strengthened the function of common mechanical steering system, has introduced automatic guidance mechanism, and has the effect of hydraulic booster, steering booster such as electric boosted concurrently.Equip vehicle of the present invention and also possessed remote control simultaneously and turn to function with automatic steering, especially be fit to the application of special vehicle.The present invention is that modern automobile improves maneuvering performance, realize the critical component of automatic steering, semi-automatic driving or remote driving, have wide practical use in the fields such as control, autonomous battlebus that turn to of medium-to-high grade car, motor dolly, various dedicated unmanned steering vehicle, intelligent combination machine, autonomous type or distance type robot.It is lighter when steering operation, more laborsaving to have equipped vehicle of the present invention, chaufeur is imperceptible to have notable difference with the conventional steering system, but when having emergency situation to occur, have automatic emergency and dodge the intervention effect of program and appear in the steering procedure, greatly reduced the traffic accident odds.When head-on crash takes place,, therefore can minimize the positive crushing injury of face evil of chaufeur owing to there is not the common deflecting bar from the steering box to the bearing circle.Under the situation that is equipped with the identity identification device, the present invention is again a kind of anti-theft device for vehicle that is difficult to crack: under the warning operating mode, bearing circle can rotate, but turning to of wheel is not cut any ice.
