Title:
VEHICULAR MOTOR DRIVE DEVICE AND VEHICULAR SEAT
Document Type and Number:
Japanese Patent JP2015204666
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular motor drive device capable of reducing influences upon a rotational speed of a motor even if a voltage of a power source is varied, and a vehicular seat with the vehicular motor drive device.SOLUTION: A vehicular motor drive device 100 includes: a motor 110; an input voltage generation part unit 120 for generating an input voltage; and a drive unit 130 to which the input voltage is inputted and which drives the motor 110. The drive unit 130 includes: a reference voltage generation part 131 for generating a reference voltage; a comparison part 134 for comparing magnitudes of the input voltage and the reference voltage; and a drive signal output part 135 which outputs a signal for driving the motor 110 at a rotational speed corresponding to output of the comparison part 134. The input voltage generation unit 120 and the reference voltage generation part 131 are configured to vary the input voltage and the reference voltage in cooperation with a voltage variation in a battery power source VB.
