System for controlling vehicle power sliding door

A system for detecting a faulty operation of a power sliding door of a vehicle, comprising:

• a motor that is supplied voltage from a power source mounted on the vehicle and operates for opening or closing the power sliding door;
• a power sliding door controller provided in a motor current supply circuit for supplying current to the motor having at least a switch for switching direction of rotation of the motor and a switching element for regulating the voltage to be supplied to the motor to change a speed of the motor rotation;
• a current detecting means connected to the motor for detecting supply of current to the motor;
• and
• faulty operation detecting means connected to the power-sliding door controller for detecting that a faulty operation has occurred in the power-sliding door controller if the current detecting means detects the supply of current to the motor when predetermined switching signal outputs are supplied to the switch to stop the motor and the switch element to rotate the motor at a speed.

A system for controlling a power sliding door of a vehicle, comprising:

• a motor that is supplied voltage from a power source mounted on the vehicle and operates for opening or closing the power sliding door;
• a motor drive circuit for driving the motor having a first switch for rotating the motor in a first direction, a second switch for rotating the motor in a second direction which is opposite to the first direction, and a switching element for regulating the voltage to be supplied to the motor to change a speed of the motor rotation;
• a motor drive circuit controller for outputting a command value to the motor drive circuit, and
• a first branch circuit provided between the motor and the first switch and a second branch circuit provided between the motor and the second switch, wherein each of the first and second branch is connected to the ground through a diode such that the diode is connected with its anode on the ground side.
