Disclosed herein is an in-vehicle apparatus having an apparatus body, a loading slot formed on the front surface of the apparatus body, a front panel arranged in front of the apparatus body, and a drive mechanism for operatively connecting the front panel to the apparatus body so as to move the front panel. The front panel is movable by the drive mechanism to a normal position where the front panel is arranged in parallel to the front surface of the apparatus body, a left projected position where a left side portion of the front panel is projected frontward, a right projected position where a right side portion of the apparatus body is projected frontward, and an open position where the front panel is inclined frontward so as to open a loading slot formed on the front surface of the apparatus body for loading a recording medium.

A memory management apparatus uses a link list memory to manage a use area and a vacant area of a data memory. The use of the use area of the data memory by each of plural ports is restricted, and the use area of the data memory is configured to be always provided for each of the plural ports. In this manner, monopolized use of the data memory by a specific port is prevented and each of the plural ports is securely provided with the use area of the data memory under control of the memory management apparatus.

A ripple detection unit detects a ripple current width of a motor current controlled according to PWM control. A ripple reference setting unit sets a reference value of the ripple current width. A frequency adjusting unit sets a control signal indicating a carrier frequency of the PWM control according to a ripple current width deviation. A carrier generation unit generates a carrier of the frequency based on the control signal. Thus, it is possible to realize feedback control of the carrier frequency for maintaining the ripple current width at an appropriate level.

A control device divides 360° corresponding to one cycle of a resolver angle into N zones, and determines whether or not a resolver angle θ in the current cycle exceeds a division border. When determined that resolver angle θ in the current cycle exceeds a division border, the control device calculates a time difference ΔT[n] between a calculation time T[n] in the immediately preceding resolver cycle and a calculation time T in the current cycle. The control device also calculates a resolver angle variation Δθ[n] with time difference ΔT[n] by adding 360° to the difference between resolver angle θ obtained in the current cycle and a resolver angle θ[n] obtained in the immediately preceding resolver cycle. The control device then calculates a rotation speed NM by multiplying, by a coefficient K, a value obtained by dividing Δθ[n] by ΔT[n].

摘要:
In a hybrid vehicle that includes an engine and a motor-generator connected to the engine through a power split device, upon acceleration in a running state, there may arise a case where the rotational speed of the MG1 enters a lockup area and, then, the MG1 cannot pull out of the lockup state with ease in such a manner that the rotational speed of the MG1 is shifted from a normal rotation area to a reverse rotation area, in accordance with an increase of a torque produced by the MG1. In this case, the engine is controlled such that a torque produced by the engine is decreased. Thus, the rotational speeds of the engine and MG1 are reduced entirely, so that the MG1 can pull out of the lockup state without increasing the torque produced by the MG1 any more.
摘要:
A sub-microcomputer having a sub-CPU and a power supply control section that controls the power supply to a main microcomputer is disposed in addition to the main microcomputer having a main CPU. A sub-clock section that supplies a sub-clock signal having a lower frequency to the sub-microcomputer can change over between a continuous mode and an intermittent mode. When the main CPU gives an operation stop notification to the sub-CPU, the sub-CPU recognizes the notification, stops the power supply to the main microcomputer, and sets the sub-clock section to the intermittent mode. The sub-CPU determines that the operation state condition is satisfied in the period of the intermittent mode, the sub-CPU changes over the sub-clock section to the continuous mode to restart the power supply to the main microcomputer.
