Abstract: To more accurately output a signal related to a source of particulate matter floating in the atmosphere, an analyzer is equipped with a mass concentration measuring unit, an element analysis unit, and a source-related signal output unit. The mass concentration measuring unit measures the mass concentration of fine particulate matter (FP) in the atmosphere. The element analysis unit analyzes an element contained in the FP. The source-related signal output unit outputs a signal related to the source of the FP on the basis of the mass concentration measurement result from the mass concentration measuring unit, and the analysis result for the element contained in the FP from the element analysis unit.

Abstract: An analyzing apparatus includes a collection filter, a two-dimensional sensor, and a calculation unit. The collection filter collects fine particulate matter included in the air. The two-dimensional sensor obtains collection image data including a collection area of the collection filter in which the fine particulate matter is collected. The calculation unit calculates data relating to content of the colored particulate matter included in the collection area based on the collection image data.

Abstract: A brake temperature detection device is configured detect brake temperature more accurately. In a situation in which the temperature in the vicinity of the brake has risen above the atmospheric temperature, indicated by a value read off of the detection signal of the temperature sensor, for example when traveling in congested traffic, a value to correct atmospheric temperature is determined, and atmospheric temperature is corrected on the basis of that atmospheric temperature correction value. Subsequently, brake temperature is calculated on the basis of the corrected air temperature. As a result of this configuration, it is possible to have the calculated brake temperature approach the actual brake temperature. This makes it possible to detect brake temperature more accurately.

Abstract: A brake temperature detection device: acquires a kinetic-energy based temperature rise, which is an increase in an amount of brake heat that occurs when kinetic energy generated in a running vehicle is converted into thermal energy by braking; acquires a braking-energy based temperature rise, which is an increase in an amount of brake heat that is calculated from an amount of work done when a brake's friction material is pressed against a friction target material; determines state of slope of a road surface on which the vehicle is running; and detects a brake temperature in accordance with an increase in an amount of brake heat generated in braking. The brake temperature detection device selects, based on the state of slope, either the kinetic-energy based temperature rise or the braking-energy based temperature rise as the increase in the amount of brake heat generated in braking and achieves brake temperature detection.

Abstract: The electric parking brake control device performs accelerator release control for moving a friction-applying member to a standby position when a vehicle starting operation is performed, the standby position being positioned between a locked position and a released position such that friction-applying member moves from the standby position to the locked position within a time which is shorter than a time required to move from the released position to the locked position. The electric parking brake control device determines whether it is unnecessary to maintain the standby position, based on whether a state in which a vehicle speed exceeds a specific speed threshold value is maintained for a predetermined period of time. The release control is performed when the electric parking brake control device determines that it is unnecessary to maintain the standby position.

Abstract: An EPB control device controlling an electric actuator driving an EPB, wherein the device performs control to reach a lock position, a release position and a standby position between the lock position and the release position. In the lock position, a friction-applying member is thereby pressed against a friction-applied member by the EPB by actuating the electric actuator and a predetermined braking force is generated. In the release position, the friction-applying member is separated from the friction-applied member when the EPB is not actuated. In the standby position, a transition to the lock position is performed in a shorter time than when the EPB is actuated from the release position by the actuation of the electric actuator. The device controls, when a starting operation to start moving a vehicle is performed, the electric actuator such that the standby position is reached.
