| description | PROBLEM TO BE SOLVED: To provide a control device for an electric negative pressure pump capable of suppressing operating noise and vibration of the electric negative pressure pump by suppressing driving frequency of the electric negative pressure pump during hill hold and of improving durability of the electric negative pressure pump while reducing electric power consumption.SOLUTION: This controller (control device) 10 for the electric negative pressure pump 11 for a vehicle including the electric negative pressure pump 11 supplying negative pressure to a brake booster 5 and a hill hold device shutting off a liquid pressure passage 8 connecting a master cylinder 6 of a brake to wheel cylinders 7 to hold braking force performs decrease control of the drive frequency of the electric negative pressure pump 11 during hill hold of the vehicle by the hill hold device. During the hill hold of the vehicle by the hill hold device, driving of the electric negative pressure pump 11 is not started. |
