Abstract: A vehicle control system configured to reduce physical stress on a driver to operate an accelerator pedal without reducing acceleration feel. The vehicle control system selects a first driving force property if an estimated stress on an ankle is less than a threshold value, and selects a second driving force property if the estimated stress on the ankle is greater than the threshold value to reduce the stress on the ankle. When the second driving force property is selected, a target driving force is reduced less than a target driving force calculated based on the first driving force property. In this case, the vehicle control system reduces a difference between: a ratio of acceleration to a pedal force given that the first driving force property is selected; and a ratio of acceleration to the pedal force given that the second driving force property is selected.

Abstract: A drive force control system controls acceleration of a vehicle accurately in line with an operation of an accelerator pedal to improve an acceleration feel. A controller calculates a corrected target acceleration when a required acceleration is large and an operating speed of the accelerator pedal is fast, and converts the corrected target acceleration into a target driving force to propel the vehicle so as to achieve the corrected target acceleration by generating the target driving force.

Abstract: One array of grindstones is used for in-feed grinding and creep-feed grinding. Therefore, it is not necessary to position a chuck table that is holding a plate-shaped workpiece with respect to two different arrays of grindstones. As a result, a period of time required to grind the plate-shaped workpiece can be shortened. Furthermore, lower surfaces of the grindstones are used for the in-feed grinding, whereas side surfaces of the grindstones are used for the creep-feed grinding. Consequently, the amount by which the grindstones are worn can be smaller than that in a case where the plate-shaped workpiece is ground to a predetermined thickness in only the in-feed grinding or the creep-feed grinding.

Abstract: Semiconductor devices that include circuitry to mitigate unstable or metastable states in logic circuits in response to receipt of an unassigned row address. The semiconductor device may include one or more logic circuits that are configured to adjust particular address-based control signals to mitigate processing based on the unassigned row address. For example, the one or more logic circuits may override processing of the unassigned row address to provide control signals that correspond to an assigned row address, which may allow the semiconductor device to operate in a known state, rather than performing operations based on an unassigned row address.
