Vehicle Driving Force Controller with Mode Select Switch

The patent applies parameter changes by providing multiple driving mode maps (first through fourth maps) with different acceleration characteristics. The driver can select from normal mode, sport mode, and other predefined modes, each with distinct throttle response curves and power delivery characteristics. This allows the driver to choose a mode that matches their skill level and driving conditions, transforming the single-parameter accelerator control into a multi-parameter system that includes mode selection, thereby reducing control nervousness while maintaining acceleration performance.

The patent implements dynamics by providing multiple driving mode maps that can be dynamically selected based on driver preference and conditions. Each map represents a different dynamic characteristic: normal mode for fuel efficiency, sport mode for maximum acceleration, and intermediate modes for balanced performance. The ability to switch between these dynamic characteristics allows the driver to obtain sufficient acceleration during high-speed running or uphill driving without requiring fine accelerator adjustments, as the selected mode automatically provides the appropriate power delivery curve.

The patent applies beforehand cushioning by implementing a mode selection mechanism that prevents sudden, unsafe transitions in driving force. The system includes multiple driving mode maps with progressively different characteristics, and the selection process is designed to avoid abrupt changes that could startle or endanger the driver. The control unit carefully manages the transition between modes, ensuring that even if an incorrect mode is selected, the driving force increases gradually rather than suddenly, thereby cushioning against potential safety issues from incorrect operation.
