VEHICLE CONTROL APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18466197 titled 'VEHICLE CONTROL APPARATUS

Simplified Explanation

The patent application describes a vehicle control apparatus with front-wheel and rear-wheel driving systems, each including a travel motor and an accumulator. A control system with processors and memories adjusts the torque distribution ratio between the front and rear travel motors based on the state of charge (SOC) of the accumulators.

• Front-wheel and rear-wheel driving systems with travel motors and accumulators
• Control system with processors and memories for adjusting torque distribution ratio
• SOC-based control of torque distribution between front and rear travel motors

Potential Applications

This technology could be applied in electric vehicles, hybrid vehicles, and autonomous vehicles to optimize traction control and improve overall vehicle performance.

Problems Solved

1. Uneven torque distribution between front and rear wheels 2. Inefficient use of energy in the driving systems

Benefits

1. Enhanced traction and stability on various road surfaces 2. Improved energy efficiency and range for electric vehicles 3. Enhanced control and performance in challenging driving conditions

Potential Commercial Applications

"Optimized Torque Distribution Control System for Electric Vehicles" could be used in electric SUVs, electric trucks, and autonomous delivery vehicles to enhance driving dynamics and efficiency.

Possible Prior Art

One possible prior art could be a patent for a similar torque distribution control system in electric vehicles filed by a different company.

How does this technology impact vehicle handling in different driving conditions?

This technology could potentially improve vehicle handling in various driving conditions by optimizing torque distribution between the front and rear wheels based on the state of charge of the accumulators.

What are the potential cost implications of implementing this technology in vehicles?

The cost implications of implementing this technology in vehicles could vary depending on the complexity of the system and the scale of production. Manufacturers would need to consider the added cost of the control system and components required for torque distribution control.

Original Abstract Submitted

A vehicle control apparatus includes front-wheel and rear-wheel driving systems, and a control system. The front-wheel driving system includes a first travel motor mechanically coupled to a front wheel of a vehicle and a first accumulator electrically coupled to the first travel motor. The rear-wheel driving system includes a second travel motor mechanically coupled to a rear wheel of the vehicle and a second accumulator electrically coupled to the second travel motor. The control system includes one or more processors and one or more memories communicably coupled to the one or more processors, and controls the first and second travel motors. When a difference between an SOC of the first accumulator and an SOC of the second accumulator is greater than a threshold value, the one or more processors change a torque distribution ratio between the first and second travel motors from a reference distribution ratio.
