Suspension Modeling

Carsim can model and simulate the suspension system of the vehicle, including the geometric characteristics of the suspension system, springs, shock absorbers and other components.

Braking System Modeling

Carsim can model and simulate the vehicle's braking system, including brakes, brake lines, brake assist systems, etc.

tire modeling

Carsim can model and simulate vehicle tires, including tire performance, friction and other factors. Simulations can be performed for different tire types, materials, air pressures, etc.

Driving Behavior Research

Carsim can simulate different driving behaviors, such as driving straight, changing lanes, overtaking, turning, etc. The influence of factors such as driver's control and reaction speed on the vehicle can be studied.

2. Development status at home and abroad

1. Overseas development status

In foreign countries, Carsim, as an earlier vehicle simulation software, has been widely used in various fields. Currently, the latest version of Carsim is 2021.1.0, which integrates multiple functions, including vehicle dynamics simulation, suspension system modeling, braking system modeling, tire modeling, and driving behavior research.

Carsim software is widely used in the development of new vehicles in the automotive industry. Automobile manufacturers use Carsim to restore various dynamic parameters of vehicles, including speed, acceleration, steering force, braking force, etc., so as to optimize vehicle design and improve vehicle performance. For example, General Motors, an American depot, uses Carsim software to analyze the vehicle dynamics and driving stability of light trucks, as well as the performance of the chassis and suspension systems in the development of new vehicles, so as to improve the quality and performance of the vehicles.

For safety performance evaluation

Carsim software can also be used to evaluate the safety performance of automobiles. Car manufacturers need to go through strict safety performance evaluation when launching new cars. Carsim can help manufacturers analyze the driving stability of vehicles in various situations, as well as the force and reaction time generated by vehicles during braking, steering and other operations. This data is critical for automakers to set stricter safety standards and improve vehicle designs.

for driver training

Carsim software can also be used for driver training. In traditional driving training, trainees practice vehicle driving on the road, which takes a lot of time and manpower. Carsim can allow students to learn driving skills in a safer and more efficient environment through a virtual simulation environment, thereby improving students' driving skills and safety awareness.

2. Domestic development status
