摘要:
An ECU determines whether or not there is an abnormality (shift pattern abnormality) in a combination of shift signals provided from a shift position sensor. After occurrence of the shift pattern abnormality is determined, the ECU determines whether or not a first condition that a shift pattern changes into a normal pattern of a drive range is satisfied, and whether or not a second condition that a vehicle is running (a driver has an intention to cause the vehicle to run) is satisfied. When occurrence of the shift pattern abnormality is determined, the ECU stops generation of driving force of the vehicle and prohibits switching to the drive range. When the above-mentioned first condition and second condition are satisfied after occurrence of the shift pattern abnormality is determined, the ECU switches the shift range to the drive range indicated by the shift pattern and recovers the driving force.
摘要:
A between-bed-and-wheelchair move assist apparatus arranged to facilitate a caregiver to help a care receiver to move between a bed and a wheelchair, said between-bed-and-wheelchair move assist apparatus comprising a support member mounted in a side rail mount hole of the bed; and a slide board mounted on the support member so as to bridge between a surface of a mat on the bed and the seat surface of a wheelchair by sliding on the mat on the bed and stretching toward the wheelchair from a position on the bed.
摘要:
A mobile station (14) transmits a connection request signal (TCCH) to a base station (12) (S102), and detects whether or not a connection response signal (SCCH) is received from the base station (12) within a predetermined period of time. If the connection response signal (SCCH) is not received within the predetermined period of time, the mobile station (14) decreases the number of subcarriers used for transmitting a radio signal to the base station (12), increases transmission power per subcarrier by an amount of power corresponding to an amount of decrease in the number of subcarriers (S104), and retransmits the connection request signal (TCCH) (S106).
