摘要: There is provided a method of specifying a location of occurrence of an abnormal sound, the method including: storing mapping data in a storage device (83), the mapping data prescribing mapping that receives, as inputs, a sound variable that matches a sound detected in a vehicle and a state variable of a drive-system device of the vehicle synchronized with the sound, and that outputs a location as a main cause of the sound; executing a sound signal acquisition process of acquiring a sound signal output from a microphone (65) that detects a sound; a state variable acquisition process of acquiring the state variable of the drive-system device; and a specifying process of specifying the location of occurrence of the sound corresponding to the sound signal using the sound variable and the state variable as inputs to the mapping. There are also provided a non-transitory storage medium and an in-vehicle device.

摘要: A control device for a vehicular on/off control valve having current control means 386 is provided. The current control means 386 is operative to allow a solenoid current IRL to be set in an operation initiating current value IRN, needed for initially switching the on/off control valve from the turn-off state to the turn-on state during a current-supplied state of a switching electromagnetic solenoid 102. It is operative to allow a sustaining current value IHD lower than the operation initiating current value IRN after the turn-on state is attained. Thus, solenoid current IRL is reduced without impairing an operation of a switching electromagnetic solenoid valve 104. Therefore, waste current can be reduced to be lower than that achieved with the conventional on/off control as shown in FIG. 8, thereby minimizing power consumption of the switching electromagnetic solenoid valve 104.

摘要: A gear-shift control data generation method executed by an execution device in a state where relational regulation data used for regulating a relationship between a state of a vehicle and an action variable associated with an operation of a transmission (26) is stored includes a process for acquiring the vehicle state, a process for operating the transmission (26), a process for assigning, based on the vehicle state, a higher reward when a characteristic of the vehicle satisfies a criterion than when the characteristic does not satisfy the criterion, and a process for updating the relational regulation data by inputting, to an update mapping, the vehicle state, a value of the action variable, and a reward corresponding to the operation. The update mapping outputs the relational regulation data that is updated to increase an expected profit for the reward when the transmission (26) is operated according to the relational regulation data.
