  • Patent number: 10612627
    Abstract: A vehicle transmission is provided that improves fuel efficiency through multiple speed stages and enhances silent drivability of a vehicle using an operating point in a low RPM range of an engine. The vehicle transmission combines three simple planetary gear units with a single compound planetary gear set or combines five simple planetary gear units to shift gears while changing rotational speeds and directions by a selective intermittence operation using rotation elements of the planetary gear units and a plurality of friction elements. Through such a shift operation, it is possible to form at least forward 10-speed or more and reverse 1-speed gear ratios for driving of the vehicle.

  • Publication number: 20200101955
    Abstract: A method of controlling driving of a vehicle using an in-wheel system includes: calculating a time to collision (TTC) by dividing a distance between the vehicle and an obstacle located in front of the vehicle by relative velocity; determining whether the vehicle enters a braking avoidance section, based on the calculated TTC; and generating, by a motor mounted in each wheel, braking force of a brake by an amount of shortage of braking force of the brake compared with a demanded braking force if the vehicle enters the braking avoidance section.
