An electric vehicle includes first and second traveling motors, first and second rotational position sensors, and a measurement controller. The first rotational position sensor detects a rotation angle of the first traveling motor and has a first wheel-speed range in which a deviation of an original position of the first rotational position sensor is measurable. The second rotational position sensor detects a rotation angle of the second traveling motor and has a second wheel-speed range in which a deviation of an original position of the second rotational position sensor is measurable. The second wheel-speed range differs from the first wheel-speed range. The measurement controller executes, in an execution order, measurements of the deviations of the original positions of the first and second rotational position sensors while the electric vehicle is traveling, and switch the execution order on the basis of acceleration or deceleration data of the electric vehicle.

The present application provides a device and a method for preventing mistakenly stepping on an accelerator by converting acceleration into braking. The device comprises an accelerator push rod mechanism, a current switch, an outer housing, a worm gear & worm mechanism and an inner housing. The accelerator push rod mechanism comprises an upper push rod, a middle push rod and a lower push rod. The current switch is provided between the middle push rod and the outer housing. A worm gear is mounted on the inner housing; a worm is mounted in the inner housing, and the upper part of the worm is provided with a centrifugal disc; a pair of pawl & iron interlocks is hinged to the centrifugal disc. The middle push rod is mounted in an axial through hole of the worm, and the outer edge of the middle push rod is provided with a ratchet wheel.

A vehicle control assembly having a control lever for controlling output of a traction drive. An operator control mechanism of the control assembly has an arm pivotable about a first pivot axis between a neutral position and a range of both forward and reverse positions. When in the neutral position, the arm can pivot about a second pivot axis between an operative and stopped position, and a switch is engaged when the arm is in the stopped position. A linkage connects the operator control mechanism to a return to neutral (RTN) module that provides a return force to the arm when it is pivoted away from the neutral position. The RTN module includes a shaft pivotable about a third pivot axis parallel to the first pivot axis and placing a magnet proximate to a magnetic field sensor chip mounted on a circuit board comprising CAN Bus and switch terminals.
