摘要： An electrical leakage determination device includes: a capacitor connected to a battery; a detection resistor connected to the capacitor; a detection unit detecting a voltage value at a connection point between the detection resistor and the capacitor; a low amplitude voltage application unit applying a low amplitude voltage to the detection resistor every driving cycle; a high amplitude voltage application unit applying, before the application of the low amplitude voltage to the detection resistor, a high amplitude voltage to the detection resistor. The device determines whether there is electrical leakage between the power supply circuit and the ground based on a peak value of the voltage value detected when the low amplitude voltage is being applied, and changes a time integral value of the high amplitude voltage applied to the detection resistor based on a change in the voltage value detected when the low amplitude voltage is being applied.

摘要： A process allocation control method is provided that controls, in a system including an in-vehicle computer mounted in the vehicle and an external computer provided external to the vehicle as nodes communicable with each other, allocation of a process related to driving assistance of the vehicle to the nodes. The process allocation control method includes: estimating an allocation risk of the process being interrupted in cases of allocating the process to either of the nodes, based on at least one of a remaining battery charge of the vehicle or a communication status between the nodes; and determining the node to which the process should be allocated, based on the allocation risk.

摘要： An object recognition device is applied to a vehicle having a range sensor that transmits a probe wave and receives the reflected wave of the probe wave. The object recognition device is configured to recognize an object behind the own vehicle based on detection information of the range sensor. The object recognition device includes a tow determining unit configured to determine whether a towed vehicle is coupled to a rear of the own vehicle, and a changing unit configured to, in response to determining that the towed vehicle is coupled to the rear of the own vehicle, change how the range sensor detects an object to suppress reception of the reflected wave caused by presence of the towed vehicle.

摘要： In a bandwidth estimation device, a measurement unit measures a measurement time from reception by a receiver of a first packet of a packet train including a plurality of packets that are sequentially transmitted from a transmitter via a communication line to reception by the receiver of a last packet of the packet train, An estimation validity determination unit compares the measurement time with a threshold time predefined based on performance of the receiver or characteristics of the communication line to determine whether a valid estimate of an available bandwidth of the communication line can be made. In response to the estimation validity determination unit determining that a valid estimate of the available bandwidth can be made, an estimation unit estimates the available bandwidth of the communication line based on an amount of data in the packet train and the measurement time.

摘要： A power converter includes a connection path electrically connecting a negative side of a first rechargeable battery, a positive side of a second rechargeable battery electrically connected in series with the first rechargeable battery, and a neutral point of windings of a rotating electric machine. The power converter further includes a control unit configured to perform switching control of an upper-arm switch and a lower-arm switch for each phase in order to transfer energy between the first and second rechargeable batteries by conducting current between the first and second rechargeable batteries via an inverter, the windings, and the connection path.

摘要： A raw material gas is supplied to a space in which a silicon carbide seed crystal is placed. A silicon carbide single crystal is grown on the seed crystal by keeping a monosilane partial pressure at 4 kPa or more and heating the space to a temperature of 2400° C. to 2700° C. The temperature of the space and supply of the raw material gas are controlled such that a temperature gradient of a growth crystal surface of the silicon carbide single crystal in a radial direction is 0.1° C./mm or less, and a radius of curvature of the growth crystal surface is 4.5 m or more, thereby producing a silicon carbide single crystal ingot having a growth length of 3 mm or more and an internal stress of 10 MPa or less. The ingot is then cut into a silicon carbide single crystal wafer.

摘要： A radar signal processing device includes an acquirer, pre-segment generator, and a segment generator. The acquirer acqu.ires ranging point information including position information and speed information at each of ranging points obtained by irradiating radar waves. The pre-segment generator generates a pre-segment by grouping the ranging points as a set of the ranging points based on the acquired ranging point information from the acquirer. The segment generator generates a composite segment by combining the ranging points from a first pre-segment with the ranging points from a second pre-segment as a set of the ranging points based on a positional relationship between the first pre-segment and the second pre-segment. The first pre-segment is one of pre-segments generated by the pre-segment generator. The second pre-segment is another one of the pre-segments generated by the pre-segment generator.
