  • Patent number: 11541959
    Abstract: A straddled vehicle has a plurality of modes for engine brake controlling. The straddle vehicle includes a mode setter that selectively sets one of at least a normal mode and a first reduced mode that are included in the plurality of modes. An engine controller controls an electronic throttle valve and a fuel injector so that a torque of an internal combustion engine is equal to a target torque. When the torque of the internal combustion engine is less than zero while in the first reduced mode, an engine brake controller corrects the target torque by adding a first additive torque to the target torque. The first additive torque is set so as to be smaller as an amount of operation of an accelerator grip becomes larger so that an opening of the electronic throttle valve increases as the amount of operation of the accelerator grip increases.

  • Patent number: 11536338
    Abstract: A self-adjusting automatic slack adjuster for reducing slack in the brake of a vehicle includes an adjuster link having a resilient portion.
