Method and arrangement for assisting in the replacement of a gearbox for a hybrid electric vehicle
Field of the Invention
The invention relates to medium-heavy and heavy-duty trucks and hybri5 electric-medium-duty and heavy-duty trucks, and in particular to assisting with the shifting of a hybrid electric-powered truck.
Background of the Invention
The importance of ventilation in construction technology has been emphasized in recent years in medium-duty trucks and heavy-duty trucks. The use of hybri10 electro-electric trucks has increased in recent years. Hybrid electric trucks usually use a combustion engine as the primary engine. Hybrid electric trucks usually also include an energy storage or energy source. The energy storage can be a chemical energy storage such as a battery or an electrical energy storage such as a capacitor battery. Similarly, an external power grid can sometimes also serve as an energy source.
The Hybrid Electric Truck can charge from the energy reserve ^ when braking the truck. This utilizes kinetic energy, which is converted into electrical energy. The energy stored in the energy storage can later be utilized for use in a hybrid electric truck.
Medium and heavy trucks, as well as hybrid trucks, have encountered the problem of shifting gears. Especially for non-synchronized gearboxes, changing gears is difficult and requires long-term accustomation. Typically, shifting may involve the use of various techniques that are difficult to control, such as intermediate gas or dual pedaling. Gear shifting situations are extremely difficult and require the driver to be precise and experienced in order to avoid traffic incidents. Often, even with an inexperienced driver, changing gears can consume too much gear.
Today, there is a clear need and demand for new types of solutions for hybrid medium-electric and heavy-duty trucks that can more easily and efficiently solve the problem of changing the gearbox of a hybrid electric vehicle or minimize the disadvantages.
