Abstract: A hybrid vehicle includes an internal combustion engine and an electric motor for powering two wheels. The wheels are separated by a common differential. A controller is provided to execute certain commands related to the braking of the vehicle. During braking of the two wheels, one wheel exceeds its slip limit, causing the wheel speed of that wheel to drop and pull-down as the wheel catches the ground. In response to the one wheel pulling-down, the controller commands a reduction of brake actuation force on the pulled-down wheel, and also commands a reduction of a rate of increase of the brake actuation force on the non-pulled-down wheel. Simultaneous pull-down or pull-up of the wheels is thereby inhibited as brake actuation forces on each wheel are continued to be controlled in response to the other wheel's activity.

Abstract: In a hybrid vehicle provided with a continuously variable electric transmission mechanism capable of sequential shift mode, a minimum engine rotational speed is specified for each gear specified in the sequential shift mode so that the lower the gear, the greater the minimum engine rotational speed. When the engine rotational speed has decreased to the minimum rotational speed while driving in the sequential shift mode, an upshift lamp of a gear shift indication device is turned on to prompt the driver to manually shift to a higher gear. As the driver shifts to a higher gear in response to the prompt, the minimum engine rotational speed is specified to a lower value. That allows for further decrease of the engine rotational speed and improves fuel consumption rate.

Abstract: Probe data is analyzed to derive Longitudinal Speed Profiles (LSPs) and an Optimal Longitudinal Speed Profile (18) for each road segment or link in a digital map network. The Longitudinal Speed Profiles (LSPs) profiles are calculated during defined time spans whereas the Optimal Longitudinal Speed Profile (18) is based on the LSP for the time span corresponding only to free flow traffic conditions. All of the LSPs can used to create a respective energy cost for each time span, or only the OLSP (18) can be used (or alternatively the RRDSL 16 or LRRDSL 17) to calculate an energy cost for the free flow conditions only. The energy cost can be used to predict the energy required by a vehicle to traverse the link. Navigation software can use the energy cost to plan the most energy efficient route between two locations in the digital map. Sensory signals can be activated if a driver strays from the Optimal Longitudinal Speed Profile (18) to achieve extremely high levels of energy efficiency.
