摘要： PROBLEM TO BE SOLVED: To prevent the driving of a drive circuit in a fault state by specifying a failure position. SOLUTION: A test voltage application circuit 13 is provided with a first relay RY1 provided between a power line 2 and the ground for driving a motor 4, third and forth relays RY3, RY4 each controlling forward and backward rotation, and a first control element FET1. The output line of the test voltage application circuit is connected with a node of the motor 4 and the fourth relay RY4. A test voltage from the test voltage application circuit is set to be a minute current outputted through a limit resistor R2. When a test is conducted by applying the test voltage before starting, only the minute current flows in the drive circuit without causing a normal driving current to flow, so that the fault state of the motor or the FET is determined based on a voltage detected by a test voltage detection circuit. Thus, an operation is suppressed before starting, and a user can be informed of an operating status. Furthermore, the occurrence of a secondary problem (an improper state) is prevented when a drive source such as a motor is driven at the time of failure. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To enable the definition of a faulty point in a driving circuit which is provided with an FET and a predriver circuit for its control.
SOLUTION: This circuit PWM-controls an FET3 which is connected in series with a motor 1 between a power line V and the ground via a predrive circuit 5 by a CPU4. This circuit is equipped with a state detecting circuit 6 which is connected to a drain of the FET and outputs a detection signal to the first input terminal I1 of the CPU, and a predrive circuit state detecting circuit 6 which monitors a gate voltage of the FET. This severally detects a signal outputted from the predrive circuit to the switching element and a signal capable of detecting the state of the switching element and compares both, so that this can determine that an abnormality has occurred on the side where the abnormality is detected if the abnormality is detected on one side of both detection signals, and therefore this can define a faulty point.

摘要： PROBLEM TO BE SOLVED: To provide an opening/closing device for a vehicle, which minimizes unnecessary motion of an opening/closing member at the time of disconnecting a clutch. SOLUTION: The opening/closing device includes an electric motor 26 for generating driving force for operating the opening/closing member, and a transmission member arranged between the opening/closing member and the electric motor 26, for transmitting the driving force to the opening/closing member. The opening/closing device is comprised of an electromagnetic clutch 31 for switching connection between the transmission member and the electric motor 26 to a connected state and a disconnected state, and an ECU 32 as a clutch control means, for controlling the driving force transmitted to the transmission member by switching and controlling the electromagnetic clutch 31. The ECU 32 gradually decreases current supplied to the electromagnetic clutch 31 to gradually disconnect the electromagnetic clutch 31. Therefore, a force released upon disconnection of the electromagnetic clutch 31 to be operated on the opening/closing member is not abruptly transmitted to the same, so that unnecessary motion of the opening/closing member is minimized.

摘要： PROBLEM TO BE SOLVED: To prevent a sliding door from being automatically opened or closed while parking on an inclined road surface to prevent a foreign matter from being caught. SOLUTION: A controller turns ON an electromagnetic clutch and drives the sliding door by a motor (S2, S3) when a main switch selects automatic opening and closing operation, stops or inverts the sliding door (S5) when a sensor detects getting-caught of foreign matter, and turns OFF the electromagnetic clutch and allows the sliding door to be opened and closed by manual operation (S7) when the main switch selects manual opening and closing operation. In this controller, the sensor detects getting-caught of foreign matter (S8) even when the main switch selects manual opening and closing operation to turn ON the electromagnetic clutch and prevent the sliding door from moving (S9) when detecting getting-caught of foreign matter.

摘要： PROBLEM TO BE SOLVED: To provide an automatic opening/closing device for a vehicle which reduces the calorific value of an electromagnetic clutch when an opening/closing member is retained at a halfway position. SOLUTION: The automatic opening/closing device comprises an electric motor for driving a sliding door to open and close, and the electromagnetic clutch for connecting a rotary shaft of the electric motor with an output shaft interlocked with the sliding door when the power is supplied. A control device switches the electromagnetic clutch to be in a connecting state by supplying the power to a clutch coil when the electric motor is actuated, and keeps the electromagnetic clutch to be in the connecting state when the sliding door stops at the halfway position. When a predetermined time passes after the sliding door stops at the halfway position, the power supplied to the electromagnetic clutch is reduced to be lower than that of the time of operation of the electric motor, by which the calorific value of the electromagnetic clutch is restrained.

摘要： PROBLEM TO BE SOLVED: To enhance operability during automatic opening/closing of an opening/closing body. SOLUTION: A position command signal Vp is composed of an output voltage by a volume 8. A pulse signal from a pulse sensor 9 for detecting an opening/ closing position of a door 3 by revolutions of a motor 4 is converted into a position-of-door signal Vd by a position-of-door calculating circuit 7b. The signals Vp and Vd are input into a main control part 7a, and a position control signal S is output from the control part 7a into an actuator 7c for outputting a normal/reverse revolution driving current to the motor 4 so as to make both of the signals Vp and Vd correspond to each other. Detection of the opening/ closing position of the door 3 by the pulse sensor 9 enables the highly accurate detection of the position. Additionally, the door 3 can be automatically moved to a position corresponding to a command position when an arbitrary position is set by the volume 8, and a switch does not have to be continuously operated until the door 3 is moved to a position where the door 3 has to be opened, in order to make the operability favorable.
