Core Viewpoint - The automotive development process involves multiple testing phases, including component testing and vehicle testing, to ensure product reliability and compliance with standards before mass production [1][11]. Component Testing - Component testing, also known as Design Validation (DV), occurs after the product design is finalized and aims to ensure that the prototype meets customer specifications and regulatory standards [3]. - Key testing areas include functional performance, environmental reliability, durability, and compliance with regulations such as crash safety and emissions [3][5]. - Specific tests for components like seats include structural stability, material durability, and safety features like seatbelt effectiveness [7][8][10]. Vehicle Testing - Vehicle testing, referred to as Production Validation (PV), is conducted before mass production to verify product quality under actual production conditions [11]. - This phase includes assessments of process stability, system functionality, and defect rates to ensure reliability and compliance [11]. - Environmental durability tests simulate various driving conditions and are critical for evaluating the vehicle's overall performance and reliability over time [13][15]. High-Performance Testing - High-performance testing involves controlled conditions to assess vehicle performance under extreme environments, such as high temperatures, high altitudes, and cold climates [15][17]. - These tests are crucial for understanding how vehicles perform under stress and ensuring that all systems function correctly in adverse conditions [17]. - Additional tests include corrosion resistance and water ingress tests to evaluate the vehicle's durability in different climates [17]. Post-Production Testing - Regular inspections, such as annual vehicle checks, are mandated to ensure ongoing safety and compliance after the vehicle has been sold [18]. - These inspections cover critical areas like brakes, lighting, and emissions to maintain vehicle safety standards throughout its operational life [18].
