Acceleration sensor for hill starting and abrupt slope slow descent

The invention discloses an acceleration sensor for hill starting and abrupt slope slow descending. The acceleration sensor comprises an inertia block, a spring piece, a left sliding block, a right sliding block, a motor, a worm and a potentiometer. The inertia block is connected with the potentiometer, and the potentiometer outputs a signal to the whole vehicle controller; the left sliding block and the right sliding block are arranged on the left portion and the right portion of the worm correspondingly, and when the worm rotates, the left sliding block and the right sliding block can be driven to move in the opposite direction or the opposite direction along the worm. The inertia block is located between the left sliding block and the right sliding block and connected to the spring piece. The motor is connected to the worm and can drive the worm to rotate in the axial direction. Compared with other gradient sensors, the acceleration sensor provided by the invention can measure acceleration only when a vehic
