Technical Field
The invention relates to the technical field of steering wheels, in particular to a driving operation execution feedback induction device.
Background
The steering wheel is a wheel-shaped device used for controlling the driving direction of a motor vehicle, and the function of the steering wheel is to convert the force applied to the edge of the steering wheel by a driver into torque and transmit the torque to a steering shaft.
The existing steering wheel of a motor vehicle has multiple functions of steering, shifting a shifting sheet, multimedia operation, constant-speed cruising and the like, but the functions are realized by lowering the head to see an instrument panel, or watching a touch screen and listening to a buzzer. These behaviors are unfriendly to the driver, and the driver is greatly improved in danger by looking at the instrument panel to confirm the operation during driving.
The motor vehicle need the driver ear to listen six ways of eight directions of sight in the driving process, but if the driver has certain hearing disorder, the effect of warning has just been lost to the buzzer on the motor vehicle, and wind noise, child noise and noisy external environment also can all influence driver's hearing simultaneously, lead to the driver to listen not to be clear the report of buzzer on the motor vehicle.
When the intelligent vehicle-mounted device is driven, a driver needs to observe a road in front of the vehicle, a motor vehicle behind the vehicle, an instrument panel, rearview mirrors on the left side and the right side of the vehicle, a rearview mirror on the road, a rearview mirror on the left side and the right side of the vehicle, a rearview mirror on the road and a multimedia screen in the vehicle, the attention is always in a highly concentrated state, fatigue driving is easy to generate under the state for a long time, potential safety hazards exist, the existing intelligent vehicle-mounted device system can replace observation of people, peripheral abnormal information can be displayed or broadcasted, and the information can be acquired only by the fact that the driver needs to see and listen.
The Chinese patent publication number is: CN205375887U, which discloses a steering wheel feedback device, comprising a frame, a steering wheel and a steering column arranged according to the real vehicle posture are arranged on the frame, a rotating shaft is connected between the steering column and a torque motor, the two ends of the rotating shaft are respectively connected with the steering column and the output shaft of the torque motor synchronously, the device also comprises a corner sensor for collecting the rotating angle of the steering wheel, the corner signal collected by the corner sensor is transmitted to a controller, the controller outputs a control signal to a motor controller, the motor controller outputs a driving signal to drive the torque motor to output a rotating torque, the corner sensor collects a signal and outputs the signal to the controller, the controller outputs a control signal to the motor controller, the motor controller outputs a driving signal to drive the torque motor to output a rotating torque, so that a trainee who rotates the steering wheel can receive a damping torque which is provided by the system and simulates the real road condition, a simulation experience can be obtained.
Although the rotating steering wheel in the above patent can obtain better simulation experience, we find that there are some disadvantages in the practical use process, such as: the steering wheel does not have the function of driving feedback, the running state of the motor vehicle and the early warning information of the vehicle machine system cannot be fed back to the driver through the steering wheel during driving, the driver is required to listen to the broadcast of the buzzer or see the vehicle-mounted multimedia screen, the efficiency is low, and the safety is poor.
Based on this, we propose a driving operation execution feedback sensing device, which hopefully solves the shortcomings in the prior art.
