Detailed Description

The advantages of the invention are further illustrated in the following description of specific embodiments in conjunction with the accompanying drawings.

Referring to fig. 1 and 2, a schematic structural diagram of a sensor housing according to a preferred embodiment of the present invention is shown, the sensor housing including:

pedal 1, pedal hinge 2

The pedal 1 and the pedal hinge 2 are cooperatively mounted as a single mechanism and provide a support plane. When the foot pressure 5 acts on the pedal, the pedal hinge is twisted and a certain torque is created on the hinge. It will be appreciated that this torque will be detected by the torque sensor 4 provided on the pedal hinge 2, and that the torque sensor 4 will form an electrical signal carrying the magnitude of the torque.

-a support device 3

The supporting device 3 is connected with a rotating shaft of the pedal hinge 2, and the supporting device 3 comprises a power mechanism and an actuating mechanism; the input end of the vehicle body control module is in communication connection with the torque sensor 4, and the vehicle body control module receives an electric signal sent by the torque sensor 4 and makes a starting or closing control instruction to the power mechanism. The output end of the power mechanism is in communication connection with the execution mechanism; the power mechanism starts or closes the actuating mechanism according to a maintaining or releasing signal sent by the vehicle body control module, and then controls the accelerator pedal 1. Preferably, the power mechanism may be a member coaxial with the rotation axis of the pedal hinge 2.

When the power mechanism receives a control command of the vehicle body control module, the intention of a user is judged according to the following conditions:

(1) if the foot is not active for a certain period of time, which indicates that the driver wishes to maintain the pedal 1 in the present position, the power means, such as an electric motor, will generate a supporting force 6 of the same magnitude as the user puts on the pedal 1, but in the opposite direction to the foot pressure 5;

(2) if the pressure from the foot 5 becomes small and exceeds a certain time, such as 0.8s-1.2s, or preferably, 1s, this indicates that the driver has taken his foot off the pedal, so that the supporting force 6 is released and the pedal 1 returns to the original position;

(3) if the foot pressure increases to a predetermined value, for example 80N-120N, or preferably 100N, the support force 6 is also released, the pedal 1 is released and the pedal 1 is moved to the corresponding position according to the foot pressure 5.

The actuating mechanism is started or closed according to the power mechanism to generate or release a supporting force 6 corresponding to the torsion, the supporting force 6 is transmitted to the rotating shaft, and the pedal is further controlled to achieve the effect of supporting the foot.

Torque sensor 4

The torque sensor 4 is connected with the pedal hinge 2 and is arranged near the pedal hinge 2. The torque sensor 4 is a detection of a sense of torsional moment on the components of the pedal hinge 2. The torque sensor 4 converts the physical change of the torque force into an accurate electrical signal. Preferably, the torque sensor 4 is an electromagnetic induction sensor, and converts the change of the torque into an electric signal reflecting the change of the electromagnetic induction intensity.
