  • Publication number: 20090095449
    Abstract: An ECU executes a program including a step of operating a battery cooling fan motor if a battery temperature is higher than a cooling required temperature, a step of sensing a cooling airflow temperature, a step of sensing solar radiation intensity onto a rear package tray, and a step of operating a motor serving as an actuator which closes a rear sunshade identified as a solar radiation blocking tool if the cooling airflow temperature is greater than a temperature threshold value and the solar radiation intensity is greater than a solar radiation intensity threshold value.

  • Publication number: 20080255716
    Abstract: A regeneration control portion sets a torque command value (in general, a negative value) of a motor generator at a time of regenerative braking. A braking cooperative control portion calculates a total braking force (power) required for the entire vehicle based on a brake depression force BK of a driver and also controls the shares of the output of the total braking force between a hydraulic brake and the motor generator. An MG-ECU drives and controls the motor generator so that a regenerative torque is generated according to a torque command value. The regeneration control portion puts a limitation such that the absolute value of the regenerative torque is smaller at a time of downhill travel than at a time of flat-road travel, for the same brake operation.
