摘要： PROBLEM TO BE SOLVED: To prevent trouble in traveling due to sensor failure by quickly and accurately detecting the malfunction of a vehicle speed sensor.
SOLUTION: Determination is made on the presence/absence of L-side (determination object side) drive output (S11), and if the drive output is not present, a counter 1 is cleared (S14), and, if present, determination is then made on the presence/absence of a vehicle speed sensor signal (S12). If a signal is present, the counter 1 is cleared (S13), and, if not, the counter 1 is made to count up (S15). Next, the speed of an R-side (non-determination object side) drive wheel is detected and compared with α (S21). If the speed is not greater than α, a counter 2 is cleared (S27), and if greater than α, the speed of a drive wheel on the determination object side is detected and compared with β (S22). If the speed is greater than β, the counter 2 is cleared (S23), and, if not, the counter 2 is made to count up (S28). After that, the counter values C1 and C2 of the counter 1 and 2 are compared with specified values CS1 and CS2 (S24), and, if C1 is larger than CS1 or C2 is larger than CS2, judgment is made that the sensor is malfunctioning (S25).

摘要： PROBLEM TO BE SOLVED: To provide a controlling method for a transport device capable of controlling the behavior of the transport device to the intended form without requiring skillfulness.
SOLUTION: The drive wheel lying inside when a bed is advanced along a curve is made controllable regardless of the turning direction or amount of handles on the basis of the relative relationship between the turning directions of a left and a right handle. In case the turning directions of the left and handles differ (S7 and S15), a regenerative braking force is given to the inner drive wheel (S17). The regenerative braking force varies in compliance with the turning amount of the handles. In case one of the two handles is operated, the inner drive wheel is stopped in the condition able to coast with inertia (S16). In case the turning directions of the left and right handles are the same, the running assist force is controlled on the basis of the mean of the handle operating amounts (S6), and when the difference between the handle operating amounts is larger than the specified value, the left and right drive wheels are controlled independently on the basis of the handle operating amounts (S4).

摘要： PROBLEM TO BE SOLVED: To provide a motor controller that is applicable to a relatively inexpensive product without impairing a fail-safe function. SOLUTION: Both first/second relays 19, 20 are off-controlled when a system power supply is turned on. A FET 18 is on-controlled for a prescribed period of time. When only a current signal I is obtained within the prescribed period of time, it is determined that the second relay 20 corresponding to a second electric motor M2 is failed. Accordingly, it is possible to detect a rotating state of the second electric motor M2 without a rotation sensor by utilizing that a sensor signal S of a rotation sensor S1 provided in a first electric motor M1 is not detected.
