Abstract
A brake pad state estimation device estimates a brake pad state including at least one of a wear volume and a temperature of a brake pad of a vehicle. The brake pad state estimation device acquires sensor detection information including a vehicle speed and a brake pressure, and calculates the brake pad state based on the sensor detection information during braking of the vehicle. The brake pad state estimation device variably sets a sampling period for acquiring the sensor detection information from a sensor according to a driving environment for the vehicle. The sampling period in a case where the wear volume or the temperature of the brake pad is expected to be lower is set to be longer than the sampling period in a case where the wear volume or the temperature of the brake pad is expected to be higher.
